and oscillogram kilogram kia I'll save

00:00:24

now I

00:00:27

'll save let's see them later hello we talked about

00:00:33

such a thing as winding pulse

00:00:35

transformers pulse

00:00:37

converter technology is now

00:00:39

found in the vast majority of

00:00:40

household and industrial devices

00:00:42

so it would be nice to understand

00:00:44

On this topic, I tried to master some

00:00:47

semi-automatic winding technology

00:00:49

close to factory quality,

00:00:51

as far as my hands allowed me, as

00:00:54

some of my subscribers could see the

00:00:56

pulse step-down converter in

00:00:57

my frequency circuit, of course you

00:01:00

can find some standard solutions,

00:01:02

for example, a set of ready-made step-down

00:01:05

modules for the required voltage and install

00:01:07

they are nearby, but it is the one-piece circuit

00:01:09

design that gives flexibility, that is, the

00:01:11

ability to easily obtain non-standard

00:01:14

voltages, for example, 16 volts, as you

00:01:16

saw at the beginning, it was a little short

00:01:19

of 16, but this is eliminated by increasing

00:01:21

one resistor. Now a small

00:01:24

thematic advertisement, you want your

00:01:26

board to be manufactured

00:01:27

professional equipment with

00:01:28

the ability to lay tracks at a

00:01:30

distance of only 0 - 15 millimeters;

00:01:32

printed circuit boards were destroyed; jelly will help

00:01:34

you in manufacturing on the website; you can

00:01:36

order boards by choosing the number of layers;

00:01:38

material; solder mask color; coating;

00:01:40

many more variations, including the production of

00:01:42

stencils for solder paste and installation of

00:01:45

components and silva; this is the first

00:01:46

Chinese company that I found out when I

00:01:48

started ordering industrial

00:01:50

production of circuit boards

00:01:51

and now let's return to our transformation. The

00:01:53

first thing we need is a frame. I

00:01:56

chose a frame of standard size E25; catalog

00:01:59

number and dimensions you now see in general

00:02:02

all the parts of the transformer; I chose from the

00:02:04

catalog ferrites and accessories for SPO

00:02:06

size E25 produced by tdk

00:02:09

good the document has all the necessary data here,

00:02:11

both on the characteristics of the ferrites

00:02:14

and drawings of the frames and all sorts of mounting

00:02:16

brackets, and so the process begins with the fact

00:02:19

that in my example, laying the first turn, it will be in

00:02:21

heat-shrinkable casings

00:02:23

and laid under the first layer, but first

00:02:25

of all, let’s take a look at the winding data: the

00:02:28

primary winding should consist of out of one hundred and

00:02:30

twenty-two turns of wire, the role of 25 here

00:02:33

is advisable to choose even a little thinner

00:02:35

since the width of the window is actually in the

00:02:37

butt

00:02:38

calculated prohibits reducing this down

00:02:40

to 0 2 millimeters in outer diameter

00:02:42

and approximately 0 16 in copper, I have a wire n

00:02:46

in 20 2 millimeters of memory and 023 in terms of the

00:02:49

outer diameter it is very tight but it will

00:02:52

fit or you will see from the raskolniks I

00:02:55

use cup tone tape about

00:02:57

10 millimeters wide with which tape I will

00:03:00

fix the initial position of the turns

00:03:02

let me not fidget in the process we fix

00:03:05

the first turn and I will be ready to wind

00:03:08

I use a homemade winding

00:03:10

machine information it is on the channel,

00:03:12

but in general these are not necessarily pulse

00:03:15

transformers; they usually do not contain a

00:03:17

large number of turns, so you can

00:03:19

do this manually or using a

00:03:20

simple mechanical machine, and so the

00:03:23

diameter I choose is 0 two hundred and thirty-

00:03:25

five millimeters; the number of turns will be

00:03:27

controlled by a counter,

00:03:28

by the way. screen calculate programs of

00:03:31

Vladimir Denisenko,

00:03:32

is anyone interested? I also have a

00:03:34

detailed video of how I did this calculation, it’s

00:03:36

called calculations, while its

00:03:38

converter is moving, I set the initial

00:03:40

position, it’s just done by eye,

00:03:42

you can correct it a little already in the

00:03:44

process, I

00:03:45

start winding very quietly

00:03:46

intermittently, I press the winding button and

00:03:48

I make sure that the turns go more or less evenly

00:03:51

after the first turns have leveled off,

00:03:53

here you can already increase the speed in the

00:03:55

video, it’s accelerated, so in reality everything is

00:03:57

slower, quality is more important there than

00:04:00

speed,

00:04:01

I set my foot to check the evenness

00:04:09

in the end, I’m a traveler, I’ll

00:04:11

squeeze in

00:04:12

the result and that’s exactly half primary

00:04:15

winding arrangement diagram the following primary is

00:04:17

divided into two halves of 600 each, one

00:04:19

turn is laid inside the secondary, then I will

00:04:22

simply connect the primary in series

00:04:24

and get one hundred and twenty-two turns, as per

00:04:26

calculation, in

00:04:28

general, the separation is done to

00:04:30

minimize leakage inductance,

00:04:32

respectively, reducing the energy

00:04:35

losses of the ferretti,

00:04:36

I will show how a little later resonant

00:04:38

transient processes are associated with the autumn,

00:04:40

this one I’ll show how it all

00:04:43

fits in with difficulty, that is, the process of filling

00:04:45

the window is very high, so I

00:04:48

recommend a slightly smaller diameter of the wire,

00:04:51

another point according to the safety rules is that an

00:04:56

insulating bandage of 3

00:04:58

millimeters from the edges should be laid on the frame is done to

00:05:01

prevent the proximity of the

00:05:02

wires of the secondary and primary when leading

00:05:05

out to the legs of the transformer in these

00:05:07

places, the windings may come into contact,

00:05:10

and even though the winding

00:05:12

wires are covered with insulating enamel,

00:05:14

this is considered insufficient by

00:05:15

standards, but in my case there is no bandage and there is

00:05:18

no place for it at all in fact, there is a

00:05:20

way to draw conclusions correctly without

00:05:22

violating the standards, I will now finish the

00:05:25

primary winding and you will all see, I

00:05:27

secure the end with smoked tape,

00:05:30

again, what kind of things did you

00:05:32

run away from me? They gave me mylar

00:05:36

vaio tape, this will be the material for the

00:05:38

main insulation between the windings In

00:05:40

my case, this one is 15 millimeters wide,

00:05:43

which is exactly the width of the transformer window,

00:05:45

I lay the insulation. When using

00:05:48

ordinary massive winding

00:05:50

wire of the PEV-2 type, it is necessary to

00:05:52

lay at least three layers of

00:05:54

insulation between the primary and secondary

00:05:56

windings. In my case, this is not so strict

00:05:59

and we are almost at the answer.

00:06:01

why complete the first half of the

00:06:03

primary winding, I put on a cambric

00:06:05

suitable for the terminal, it is not fireproof in any

00:06:08

way, in fact, it will have nowhere to go

00:06:10

after wiring the terminals,

00:06:12

now you need to wind the secondary windings, and

00:06:15

here I use pro in the so-called

00:06:17

double insulation,

00:06:18

these are actually sold, including on

00:06:21

aliexpress and its meaning is that it is

00:06:23

certified for a very high

00:06:25

impulse breakdown voltage, this gives

00:06:27

us the right not to be afraid of the penetration of

00:06:28

high voltage from the primary winding

00:06:31

into the secondary, even taking into account the absence of the

00:06:33

proper rings and the reduction in

00:06:35

interlayer insulation, I tried to

00:06:37

determine and

00:06:38

there were three layers for a discount I saw some

00:06:40

external transparent film and gave the

00:06:43

main insulation,

00:06:44

apparently under another layer of film, at

00:06:46

least the structural diagram of such

00:06:48

wires tells us about this by the way, you

00:06:50

knew that the Japanese use inverted

00:06:52

Roman numerals, this is one, this is two, this is

00:06:56

three,

00:06:59

after finishing studying Japanese numerals,

00:07:02

I begin to wind the secondary winding and

00:07:04

first we have 13 turns for the gate on

00:07:06

running transformers and, in general, for

00:07:08

pulse transformers, the phasing of the windings is important,

00:07:10

that is, their winding directions

00:07:12

relative to each other, and so if you

00:07:14

make the water in a different order,

00:07:15

the converter will not work; these

00:07:18

relative directions are usually

00:07:20

shown by dots on In the schematic

00:07:22

diagrams, let's wind these 13 turns; in fact,

00:07:26

winding a thick wire is much easier; it does

00:07:28

not tend to overlap and

00:07:30

almost always lies flat, as I already said,

00:07:32

winding this by hand does not present

00:07:34

any problems and again I secure the end

00:07:37

with cardboard tape, take out the

00:07:40

crumbs and secure everything again on top

00:07:44

for the next operation we will need a

00:07:47

bandage tape, in my case it is

00:07:49

2 millimeters wide and 0 2 millimeters thick,

00:07:52

but as I already said, it would be nice to have

00:07:54

another bandage 3 millimeters wide for winding windings

00:07:56

of purely classic

00:07:58

enameled wire, in my case

00:08:01

the bandage is needed to fill an empty

00:08:03

space where there is no windings, this is done to

00:08:05

equalize the height of the word and in the future

00:08:08

reduce the bumps on the layers, this is

00:08:09

how it will look, of course it won’t be

00:08:12

possible to do it perfectly evenly, at

00:08:14

least you need to try, then I make a

00:08:19

layer of mylar, it’s here more for order

00:08:21

than for insulation, I

00:08:32

start winding another one

00:08:34

here, I need to first wind 7 turns

00:08:37

onto the leg, then another 10 and

00:08:40

again, I do everything according to the previously written

00:08:42

algorithm, wind, fasten with a cup tone,

00:08:45

do from here and so on, since

00:08:48

uneven layers

00:08:50

will accumulate due to the presence of bends, the evenness of the winding

00:08:52

will of course suffer a little from this, but

00:08:55

in principle, this does not matter, the main thing is that it

00:08:57

corresponds to the number of turns

00:09:25

and again I fill the bandage tape with

00:09:27

part of the unused space of

00:09:29

the window, this is also important since on top I still place a

00:09:32

layer of thin wire

00:09:35

my mail of the

00:09:36

first tape now I have significantly

00:09:38

increased this is my attempt to maximally

00:09:40

level the place for laying the next

00:09:42

layer

00:09:47

now the final stage is another

00:09:49

sixty-one turns of wire with a diameter of

00:09:51

023

00:09:54

here, first I lay it half

00:09:56

by hand, the main thing is to fasten a couple of turns

00:09:58

and then it will go,

00:10:19

and even with a very severe sleep curve it’s

00:10:21

not possible to wind it quite well, I

00:10:24

took a couple of macro photos to

00:10:25

admire the result

00:10:31

further after the

00:10:33

last ones were secured we also put on the cambric coils and

00:10:36

make the last layer of my yard

00:10:38

insulation,

00:10:51

as a result we have this porcupine

00:10:53

star,

00:10:54

all sides with wires, carefully

00:10:57

clean the ends, wind them on the leg,

00:10:59

solder them,

00:11:07

I got this design

00:11:09

now a little magnetic circuit, these are 2 tails

00:11:12

made of n 87 material,

00:11:14

they are different 1 tail with a gap of the sea

00:11:16

millimeters and the second with a gap of 0 25

00:11:19

millimeters and in the end the total gap

00:11:21

is equal to 0 25 millimeters,

00:11:23

this is visible in the light, I highlighted

00:11:29

the lines with the necessary false

00:11:31

numbers,

00:11:32

by the way, by combining boxes with different

00:11:34

gaps you can get a whole bunch of

00:11:36

options for the final magnetic

00:11:37

permeability, this is how it all turned out I

00:11:41

just I used Milo to tighten

00:11:43

the magnetic core in this form, it doesn’t

00:11:45

stick tightly to the frame, it’s

00:11:47

still advisable to glue it, and now

00:11:50

the most interesting tests, the first test

00:11:53

will show us the inductance of the primary

00:11:55

winding and the Chinese Rolls meter

00:11:57

shows us three point eight four

00:11:59

hundredths of a milligan ri, this is very close to the

00:12:01

calculated value if we are to be accurate, then

00:12:03

it will be less than five percent error;

00:12:06

another interesting experience is measuring the

00:12:09

inductance of the plant; for this I am for

00:12:12

Karachev, both secondary windings here are the

00:12:14

wiring, just connecting the beginning to the end,

00:12:17

so for both windings and after that I

00:12:19

measure the inductance of the primary again,

00:12:22

getting 50 microgen or the

00:12:25

lower this number, the better

00:12:26

the setting, saying we need this value

00:12:28

only for information in the calculations, it is

00:12:31

explicitly involved in it; it may also be

00:12:33

required when modeling such a

00:12:35

converter. The inductance of the plant

00:12:38

determines the magnitude of the voltage surge

00:12:39

when the transistor is closed and also affects the

00:12:42

intensity and frequency of resonant

00:12:44

oscillations after closing, we will

00:12:46

look at this in more detail

00:12:48

so that we have something to check on. I assembled a

00:12:50

test bench based on a

00:12:52

frequency driver board where I placed only the parts

00:12:54

related to the flyback

00:12:56

converter PWM controller

00:12:58

steppe 1200 chip at a frequency of 60

00:13:01

kilohertz

00:13:02

in this series there are also options for 40 to

00:13:04

100 kilohertz, for example, at a standing position at that

00:13:07

time I did not find it on sale,

00:13:08

although in fact I wanted exactly 100

00:13:10

high frequency, they are interesting specifically for

00:13:12

low-power power supplies and in theory

00:13:14

will give less output

00:13:16

voltage ripple, of course, not all fillets can

00:13:18

work at such a high frequency, but

00:13:20

specifically n 87 goes up to 100 kilohertz

00:13:23

is possible and then I’ll buy a couple of

00:13:25

microcircuits for this frequency and so I need to

00:13:29

assemble a

00:13:30

prototype board and in fact soldering on a

00:13:32

factory dress is a pleasure, but

00:13:34

if I have a lot and then understand a couple of

00:13:36

hundred standard sizes 0805 this is already

00:13:38

becoming stressful, by the way I want

00:13:40

to try how- some kind of wiring of SMD

00:13:43

components in China is a very interesting

00:13:45

experience, such as I think in general, as I already

00:13:48

told, the miniaturization of electronic

00:13:50

components is one of the main trends in

00:13:52

the development of electronics and gradually everything

00:13:55

from a resistor to a transistor for

00:13:57

hundreds of amperes will be located in a

00:13:59

package the size of a coal eye from

00:14:02

this there’s no escape, and that means whether you want it or

00:14:04

not, you have to master

00:14:05

automated assembly technologies, some

00:14:08

components with massive leads need to be

00:14:10

soldered at elevated temperatures, I

00:14:12

try not to overheat the

00:14:14

long-term temperature above 300 degrees, that is,

00:14:16

I have two hundred seventy-five

00:14:18

degrees of normal temperature, three hundred

00:14:20

twenty-five degrees in short-term

00:14:22

boost mode and 350 360 I install

00:14:26

manually for particularly fatty parts,

00:14:28

but then I immediately reset them back. As a result, I

00:14:31

soldered the power supply parts together

00:14:33

with the network capacity. At the same time,

00:14:35

I provided for the possible quick

00:14:37

replacement of the transformer and transistors for

00:14:39

carrying out various tests

00:14:41

of experiments, and here we come to

00:14:45

The most interesting thing is that I turned it all on and

00:14:47

output a signal from all legs of the transistor, then the

00:14:50

yellow beam

00:14:51

is the drain of the transistor, the blue beam is the source

00:14:53

and the red one is the gate, let's

00:14:54

start understanding the yellow one, they teach

00:14:57

high voltage there in my case 456

00:14:59

volts from peak to peak, this value

00:15:02

should not exceed the maximum permissible

00:15:04

for a transistor in my case is 600

00:15:06

volts and that means everything, but here I translated

00:15:10

the diagram and articles explaining the resonant

00:15:12

transient processes in the reverse host,

00:15:14

immediately after the transistor is closed, an

00:15:16

oscillatory process begins between the

00:15:18

inductance in plants and the capacitance of the

00:15:20

closed channel of the transistor. Earlier, we

00:15:22

already measured the leakage inductance

00:15:24

is about 50 henry, at the same time we

00:15:28

can still determine the frequency of these

00:15:30

resonant oscillations, it is

00:15:32

about 3 megahertz, I know the frequency,

00:15:34

inductance, we can easily determine the

00:15:36

capacitance of a closed junction,

00:15:38

for example, you can use a

00:15:39

calculator in general in engineering

00:15:41

practice,

00:15:43

some kind of calculator is constantly used to calculate or

00:15:45

simulators, this is all very speeds up the

00:15:47

development process and makes the results very

00:15:49

accurate and the calculated capacitance of the

00:15:52

closed channel is 56 picofarads

00:15:54

and now let’s compare this with the data table for

00:15:57

the transistor and see like I’ll increase it at the

00:15:59

level of 67 picofarads, which

00:16:01

means our representation is very close

00:16:03

to the truth. The following oscillations are the

00:16:06

resonance of the main inductance of the

00:16:08

primary windings with the same

00:16:10

parasitic capacitance of the transistor channel,

00:16:12

since the inductance of the winding is much

00:16:14

greater than the leakage inductance, the

00:16:16

frequency of these oscillations will be much

00:16:18

lower and they can continue until the start of the

00:16:20

next cycle, the moment these

00:16:23

oscillations begin depends on the total load of the

00:16:25

power supply, in my case I

00:16:27

loaded all the outputs well and cool do not

00:16:29

start late enough and it is not very

00:16:31

convenient to evaluate their purity and since not a

00:16:33

single full period fits,

00:16:36

although I can say with complete confidence

00:16:37

that it will be about 340 kilohertz,

00:16:40

another parameter that can be assessed

00:16:42

is the maximum current through the

00:16:44

transistor channel; we will only make an assessment

00:16:46

by in the blue graph this is the

00:16:48

voltage drop across the resistance r 40 one

00:16:50

and a half minds, from here we divide the peak

00:16:53

value of 656 millivolts by one and a half minds and

00:16:56

we get a peak current of the order of four hundred

00:16:58

thirty-seven milliamps miscalculation

00:17:03

this value should be about three hundred

00:17:05

sixty-four milliamps

00:17:06

in fact I also received large

00:17:08

peak current values but in general

00:17:10

the order lies within 2 amperes, which

00:17:12

means again this is all very close to

00:17:14

expectation, although perhaps I don’t quite

00:17:16

understand this value correctly, perhaps

00:17:18

you need to look at the current at the end of

00:17:20

saturation of the primary winding and then at

00:17:22

this point there will be just the calculated 364

00:17:25

milliamps, I think it’s correct so

00:17:28

there is something else very interesting, this is

00:17:31

how the PWM controller controls the gate and

00:17:33

now I will demonstrate this,

00:17:36

you can see that the maximum

00:17:37

voltage on the gate is constantly jumping

00:17:40

and this could be mistaken for random

00:17:42

changes, but this is not so, this

00:17:44

control method has a completely periodic

00:17:46

nature and if we Let's expand the graph onto

00:17:48

a large time axis and see a triangular

00:17:50

shape of the maxima of the signal, that is, you will attach the

00:17:53

degree of opening of the channel to me, as if swaying,

00:17:55

from periods to periods,

00:17:58

increasing then again decreasing

00:18:00

accordingly, and the current through the transistor

00:18:01

will follow a similar law.

00:18:03

By the way, I don’t know whether this is typical for

00:18:05

all bus controllers or is it just

00:18:07

feature of this microcircuit, if anyone

00:18:09

knows a clear article on this topic, then

00:18:11

write in the comments and finally

00:18:13

let’s see that the blue output is

00:18:15

now installed after the filters on the

00:18:17

16 volt line and switch the

00:18:20

AC mode, this allows me

00:18:22

to see the peak ripple levels of this

00:18:25

from peak to peak at nominal

00:18:27

ripple load 200 44 millivolts

00:18:31

is actually a lot, but specifically in this

00:18:33

case it is not at all important since

00:18:35

this power supply is part of a frequency

00:18:36

converter and there are enough sources of interference in it

00:18:39

without this, so there is

00:18:41

nothing to spoil here, although in fairness

00:18:43

there are also direct ones and in an indirect

00:18:46

way to reduce these output

00:18:47

ripples, I just didn’t use all the possible

00:18:50

methods; the first and the simplest

00:18:52

is to increase the capacitance of the output filters

00:18:55

and increase the inductance; the second method is to

00:18:57

introduce from number circuits as well as

00:18:59

ferrite beads; beads are generally an

00:19:01

interesting topic; perhaps it’s worth

00:19:04

exploring in more detail the meaning in in

00:19:06

order to reduce the causes of pulsation,

00:19:08

namely the high current peak when opening the

00:19:10

mosfet, and it is the influence of this

00:19:12

peak that has the maximum effect on the output

00:19:14

pulsations, and of course there is also a separate

00:19:17

topic with shielding the primary winding

00:19:19

on a serial power supply; the presence of taps

00:19:22

is good form, I think this is not

00:19:24

so difficult to do at hand means you

00:19:26

will only need to find thin copper

00:19:27

foil and wrap it in maillot. It will also

00:19:32

remain interesting to disassemble these

00:19:34

oscillations, what is their nature and

00:19:36

what the intensity and frequency depend on,

00:19:39

since from what I see this is what

00:19:40

is transformed then into the secondary

00:19:42

winding and becomes a harmful pulsation and

00:19:44

Another moment how all this is connected with

00:19:46

this voltage step on the gate

00:19:48

while in thought

00:19:50

in general and in general in this video we

00:19:52

figured out the technology of winding

00:19:54

pulse transformers

00:19:55

and these techniques can also be successfully

00:19:57

applied to something different from the

00:19:59

reverse ha come on like this direct running

00:20:02

floors, pavements, and so on, pulse

00:20:04

converter technology is now

00:20:06

developing by leaps and bounds, a

00:20:09

huge

00:20:11

number of topologies have appeared, and even the reverse

00:20:12

running has acquired its

00:20:14

continuation in the form of quasi-resonant

00:20:16

converters, so good luck with your

00:20:18

developments and thanks for watching bye
