see you on our channel and today we

00:00:04

again have an interesting topic in this video we

00:00:07

will find out how in electronic devices we

00:00:08

get a higher voltage from a

00:00:11

lower one, we will talk about

00:00:13

step-up DC converters,

00:00:15

we will understand how they work and let's assemble

00:00:17

our own step-up converter that

00:00:19

will give us such a high voltage that it

00:00:21

can even from the sponsor of today's

00:00:23

video our faithful friends the Jersey company

00:00:26

itself is not really pleasant

00:00:28

to advertise because they do such a good

00:00:30

job for only 2 dollars these

00:00:32

guys will make for you up to 10

00:00:34

double-sided printed Factory-

00:00:36

quality silk-screen printing boards and a mask Let me remind you

00:00:38

that recently they no longer charge the

00:00:41

fee for different colors of the mask, choose

00:00:43

one of the proposed colors and the boards

00:00:45

will also cost 2 dollars. To

00:00:46

place an order you need to create an archive of

00:00:48

gerberas with files in the program in which

00:00:50

you created your printed circuit. fee and

00:00:52

put it on the Jersey website by yourself.

00:00:55

com, well, you will find a link to their website in the

00:00:57

description, go to step-up dc-dc

00:01:00

converters work thanks to the

00:01:01

amazing properties of

00:01:03

inductors or a choke, bypassing

00:01:06

radio components, I talked in detail in the

00:01:08

previous video, there I tried

00:01:09

to explain how it works in

00:01:11

electrical circuits,

00:01:12

but now let's figure out how

00:01:14

boosters are designed converter and we have a

00:01:16

power supply,

00:01:17

inductor and transistor, all these parts are

00:01:19

connected in series into one circuit of the

00:01:21

transistor, we also add a PWM

00:01:23

controller that will turn on and

00:01:25

off the conductivity of the transistor many

00:01:27

times per second, for clarity, I

00:01:29

depicted the transistor on the diagram in the form of a

00:01:30

button so that you can see what it is in in the

00:01:33

default state, the transistor is closed and

00:01:36

no current flows in the subcircuit, but when the transistor

00:01:38

opens briefly, the inductor

00:01:40

begins to saturate its magnetic field,

00:01:42

after the inductor has saturated its

00:01:44

magnetic field, we open the

00:01:46

transistor circuit and due to the properties of the inductor,

00:01:48

which I talked about in the previous video, the

00:01:50

voltage in the circuit begins increase and

00:01:52

we can remove this increased

00:01:54

voltage by adding a diode and a capacitor to our circuit

00:01:56

and everything will work

00:01:58

as follows: the

00:01:59

circuit is open and nothing happens

00:02:01

for a moment in

00:02:03

the transistor at this moment the inductor

00:02:04

will recharge or rather saturate its

00:02:06

magnetic field and as soon as the transistor

00:02:08

is closed a circuit will appear high

00:02:10

voltage that is already waiting for the

00:02:12

capacitor, let me remind you that the inductor

00:02:14

is connected in series with the main

00:02:16

power source, their voltages

00:02:18

are summed up so that the charge does not enter from the

00:02:20

capacitor when

00:02:22

the transistor is open, a diode is added to the circuit in

00:02:24

which, as everyone knows, conducts current

00:02:26

only in one direction, we will repeat

00:02:28

this cycle thousands of times per second of the

00:02:29

escaped controllers and the speed of

00:02:32

the transistor, and in the end we get a

00:02:34

pulsed high voltage that is

00:02:36

smoothed out by capacitors. To prove

00:02:38

the veracity of my words, I assembled a small

00:02:40

circuit of the same boost

00:02:41

converter. The power source will be an

00:02:44

ordinary battery bank 18,650

00:02:47

capacitor, I use a

00:02:49

one-microfarad film capacitor as a shim. -controller,

00:02:51

we will have an arduino stitched with a sketch

00:02:53

that makes it generate a PWM

00:02:55

signal on the ninth pin.

00:02:57

We will control the duty cycle with this

00:02:58

potentiometer. The PWM frequency is set to

00:03:00

sixty-two and a half kilohertz. By

00:03:02

rotating the potentiometer knob, we see how the

00:03:04

voltage increases because

00:03:06

by increasing the duty cycle of the PWM signal,

00:03:08

the transistor is passed through the choke

00:03:09

has longer pulses and

00:03:11

josie saturates its magnetic

00:03:13

field more strongly and, as a result, it produces more

00:03:15

powerful response pulses; it does not

00:03:17

raise the voltage higher, trying to close

00:03:20

so that there is no doubt that the

00:03:21

increase in voltage is due to the

00:03:23

choke; they are due to witchcraft or - for

00:03:25

my cheat, we will replace the transistor in

00:03:27

this circuit with an arduino button on my

00:03:30

finger and in this case we also see an

00:03:32

increase in voltage, of course my finger is

00:03:34

not as fast as arduino and I do not

00:03:36

press the button 62 thousand times per second,

00:03:37

so the increase in voltage is not so

00:03:40

great but very clearly visible to

00:03:42

compensate for my slowness, we can

00:03:44

use a choke with more

00:03:45

inductance much larger, a choke with

00:03:47

more inductance needs more

00:03:49

time to saturate its magnetic

00:03:50

field under the same conditions,

00:03:52

unfortunately I don’t have such a choke, but

00:03:54

I do have a high-voltage transformer,

00:03:55

by the way, this is a small spoiler for

00:03:58

one of our next videos so

00:04:00

subscribe, the

00:04:01

secondary winding of this transformer

00:04:03

has a very high inductance and we

00:04:05

can use it as a friend and just

00:04:07

something that we cannot

00:04:08

even after a single use. on the button we

00:04:10

see an increase in the voltage on

00:04:12

the capacitor at times

00:04:13

and the prize is successfully pressed, we can already

00:04:16

light up a small neon

00:04:17

light bulb a little to get a

00:04:19

more serious voltage, we will return to the transistor with

00:04:22

arduino and the chokes have less inductance,

00:04:24

but we will use not a single can of

00:04:26

18 650 power supply for 12 volts

00:04:30

for me We also had to install

00:04:31

two capacitors in series to

00:04:33

prevent breakdown because the

00:04:35

voltage promises to be high. By rotating the

00:04:37

potentiometer knob, thereby increasing

00:04:39

the duty cycle, we easily get

00:04:41

close to the 600 volt mark, which, by

00:04:44

the way, is greater than the calculated voltage of

00:04:46

this transistor to 35 68, but it stays

00:04:49

that way with such voltage can already

00:04:51

scare a person so well and therefore do not

00:04:53

repeat what I will do next

00:04:55

[music]

00:05:00

all of this, of course, is coolly high voltage

00:05:03

and hidden, but this is an ineffective

00:05:05

homemade solution; a more serious solution with

00:05:07

high efficiency and a stable output

00:05:09

voltage is usually built on

00:05:11

specialized microcircuits, for example

00:05:13

excel 6009 or the very popular lm 2577

00:05:16

such microcircuit works under exactly the

00:05:19

same principle described earlier, but the

00:05:21

PWM controller transistors are built into the

00:05:23

microcircuits; I also have a

00:05:25

reference voltage circuit; the

00:05:27

output voltage from the converter and the

00:05:29

duty cycle of the pulses are compared with it; the PWM signal is

00:05:31

constantly adjusted to maintain the

00:05:33

specified output the voltage is stable

00:05:35

on the basis of similar microcircuits,

00:05:37

all step-up 10 se converters are built in

00:05:40

various equipment from toys where you need to

00:05:42

increase the voltage of batteries to all kinds of

00:05:44

computer equipment, even step-up

00:05:46

dc-dc converters can be bought on

00:05:48

aliexpress in the form of a board

00:05:49

they have contacts for input and

00:05:51

output voltage the ability to

00:05:52

adjust the voltage and in some

00:05:54

options,

00:05:56

I will leave links to such scarves in the

00:05:58

description for adjusting the output current; they can be useful for

00:06:00

amateur radio needs, and this is where our
