that should be supplied in harmony in blocks,

00:00:04

then here the voltage is constant which

00:00:08

supposedly comes out of the power teeth

00:00:14

[music] I

00:00:20

welcome everyone to my channel,

00:00:22

dear viewers and subscribers, in this

00:00:26

video clip I want to tell you about

00:00:30

such a circuit, this is a switch of

00:00:34

transformer windings, I’ll immediately say that the circuit and the

00:00:39

printed circuit board was taken from the channel and as an

00:00:42

Asian I will leave a link to a video clip with its

00:00:48

production and its version in

00:00:52

the description since I don’t want to violate the authorship

00:00:56

and appropriate it for myself, especially since

00:00:59

you can download all these files from him,

00:01:03

the sources of my version in principle everything is the

00:01:08

same, only I installed the zener diodes

00:01:10

at 5 1 volts since

00:01:14

I use a transformer with windings of 6 3

00:01:17

volts, that is, ideally,

00:01:19

first 6 3 volts goes to the alternator, then the

00:01:24

voltage increases, the voltage

00:01:27

increases to 12 and 6 volts and another

00:01:30

stage is

00:01:31

already increases to 20 volts, now I

00:01:36

will demonstrate this to you, so this means that my

00:01:42

power supply by the way works,

00:01:45

this circuit works for me at 12 volts video about

00:01:49

Kasyan said that she needs to supply 18 volts at

00:01:52

least although the purpose is to use

00:01:55

12 volts and it works from 12

00:01:59

the only caveat what is this and the circuit

00:02:02

needs a separate voltage source

00:02:05

for which I need this channel of the

00:02:06

power supply; channel 2

00:02:09

acts as an output source,

00:02:16

that is, here

00:02:20

a plus is supplied to the zener diode so how can I

00:02:23

place everything here on our

00:02:27

multimeter

00:02:29

on a multimeter My voltage

00:02:33

is shown in such a way that nothing is

00:02:36

visible, here on the multimeter there is a

00:02:43

variable voltage that should be supplied to the

00:02:46

power supply board, here the voltage is

00:02:49

constant, which supposedly comes out of the

00:02:52

power supply, turn the click of the switch, the

00:02:58

voltage clicked 13 7 volts and then turn the

00:03:03

knob, when the voltage is about 12 volts

00:03:12

it works the second relay and the voltage is already

00:03:15

20 volts, the same thing is applied and in

00:03:21

reverse order, this circuit is designed to

00:03:27

reduce the power dissipated by the

00:03:30

transistor in a linear power supply,

00:03:34

the circuit works well, the relays click, the

00:03:40

windings switch and everything would be fine, but

00:03:46

unfortunately there is,

00:03:48

but this is but I’ll show you now but first,

00:03:59

let's go over the circuit a little;

00:04:03

the circuit, however, is actually simpler than

00:04:06

simple,

00:04:10

as Kasyan said, this unit with a

00:04:13

transistor and a resistor, this

00:04:15

zener diode can be excluded from your

00:04:20

circuit; I didn’t use it; I only have

00:04:23

two zener diodes; the

00:04:28

zener diodes themselves are selected according to the required

00:04:30

voltage by about a little a little lower than the

00:04:36

voltage of the voltage of your transformer winding, the

00:04:43

output from the power supply is supplied here and the

00:04:52

circuit is powered by a separate source,

00:04:55

but 18-20 volts, I think it’s still too

00:04:59

much here, 12

00:05:04

volts of constant voltage for the relay was enough for me and

00:05:08

everything worked fine when the voltage

00:05:13

exceeds the opening level of the zener diode the

00:05:19

current flows through the resistor opens the first

00:05:25

transistor transistor in turn turns

00:05:28

on the relay,

00:05:37

then the voltage increases and

00:05:44

opens the second zener diode and 2

00:05:48

zener diode

00:05:49

in turn opens the second

00:05:52

transistor and the transistor turns on the second relay here are the

00:05:55

relay windings,

00:05:58

that is, but here 12 volts goes in

00:06:01

my case 6 3 volts but then I

00:06:03

changed it but you will see about this in another

00:06:06

video 12 volts initially goes like this and

00:06:11

goes to the output then we have 1 relay when

00:06:16

it turns on we no longer get 12 volts but

00:06:19

24 volts and then the second relay turns on

00:06:25

and it’s already full the voltage on the circuit

00:06:31

first plays at this time open

00:06:34

in order to turn off 1

00:06:39

relay and this is the chain that serves,

00:06:44

but it doesn’t bother me much and in my

00:06:49

case one relay was already used so that’s why

00:06:51

I didn’t use it, but

00:07:00

now let’s talk about it small,

00:07:02

but I want to use this circuit with this board,

00:07:07

so we have a

00:07:14

voltage regulator here on the multimeter, I get the

00:07:21

output voltage from the board and now I

00:07:25

also have a transformer at the output of 3 volts,

00:07:33

increasing the voltage, by the way, I

00:07:39

don’t know why there were three tables,

00:07:41

this is the minimum and that is,

00:07:46

6 3 volts are now supplied to the input, we turn

00:07:55

it further, the winding switches,

00:07:57

firstly, 976 volts, the

00:08:03

voltage jumps, but this is most

00:08:06

likely a problem with the board itself, for some reason it

00:08:09

reacts this way to such a difference in the input

00:08:12

voltage,

00:08:13

but now the switch clicked, but

00:08:18

everything is fine with the voltage, then I removed it

00:08:22

the voltage is lower and for some reason the relay

00:08:28

starts clicking back and forth, I

00:08:32

have to remove the voltage to 0

00:08:37

again, this is the first stage, stage 2,

00:08:50

we reduce the maximum output voltage,

00:08:58

but

00:09:02

until I turn it down to 0, the relay won’t stop

00:09:07

clicking like that, that is, now I of course

00:09:11

I’ll try to

00:09:12

figure it all out, I’ll try to

00:09:15

conjure something,

00:09:18

I don’t know what yet, but there is such a problem with this

00:09:23

board, I

00:09:26

can’t say why yet, well, but in

00:09:31

general the circuit itself is simple and, in

00:09:35

principle, working, that is, from voltage

00:09:38

it works, switches the windings,

00:09:41

perhaps with another board, it’s simple,

00:09:45

for example, on lm317 with external transistors,

00:09:48

everything will work as expected, well,

00:09:53

thank you all for watching

00:09:55

the link, it means the author’s video, I’ll leave

00:09:58

some in the description for the components, too, if you drop

00:10:03

links, go ahead and buy them,

00:10:09

wait for new projects, thank you all for

00:10:13

watching, like and subscribe to
