 Hey, hi guys, I debating the baby over to make a little video about this build, but I Decided there's a start here I'm a bit of a zvs draw the zvs zv s zero voltage switches Italian invention, I think all of his own I've got some parts. This is a these are cooker These actually come off you combine from China these zvs drivers They're cooker This one the case got damaged, but I have done the checks on it. It's still okay Well, I've got a couple of these as well to give these a go higher No, they're not they're a slightly four hundred and seventy Nanofarads and 600 volts where these are 1200 volts AC or DC and 600 volts AC resistors resistors 12 volt diodes of course in ducte this one is 90 milliheners I understand anything between 40 and 200 is good Yeah, I'm gonna actually build it onto this board This is where my these two prongs For the Jacobs ladder normally go and I'll just move those down a bit so I can fit the flyback here and Yeah, we'll give it a go I don't think I'm gonna do the build recording it I'm gonna do is just move the stuff out the way and just get on and build it and then put it on Put on the video for the test Let's see how it goes Hey, so what I built it I built it. This is basically a design you find on the internet Schematic you find on the internet and it seems to be the basic So like 10 amp ZVS driver zero voltage switching circuit So all you know is for like Stick a flyback on there give it some power See if this baby actually works I Hope I've got this right You know, I've looked at it's got a few times. I hope I got it right. I've been drinking You shouldn't hey kids any kids watching don't be messing about with electricity and such and drink Because that's when you you know, you're an idiot like me you end up having some sort of problems or Such with nothing so far Yeah, so I hope it's okay. I think I've got it right It looks sort of okay as long as I've got this gate Drain and sourcing I got my pal coming into the gate It's got this little zoono diet in this sort of like Just like a voltage lashing system This comes up to the side to the gate And the drains going out via the capacitor Yeah Yeah drains going out to the Why will plug into it will be the coils Which then go on to the fly back in a coil on a fly back And then the source pins Which goes off to negative did this is not color coded as such. I mean it Maybe sort of but this isn't because it's just I run out of I wasn't gonna keep cutting up this Brown wire just to put some Some color coding type thing on there Anyway, honey, I don't think I'm gonna power this right now. I think what I want to do is Actually look at it again in the morning When I stop this I'm gonna go and plan my game now for a little while Put myself to bed So I'll check it again in the morning, and then we took some power through it very things. Okay, let's see what it does by Okay, so I'll build this thing up and It gave me an indication on the power supply that was just shorting out So I'm taking that apart Well, I'm not taking it all completely apart. I'm now This is the bit of an electronic switch Although it's nice to have You know success This is this is what we play for troubleshoot Troubleshoot so now I do just figure out what this thing doesn't work I've looked over the circuit. I've looked over it over it and over it Unless I'm missing something I've got a component down Diodes I Don't know but this is it now. This is the fun part of the troubleshooting I don't know how long this is gonna take me how many times I'm gonna go back to the circuits How many times I'm gonna look at different circuits just to double-check this and I've already noticed a difference on one circuit to this being exactly the same thing Is that the resistors are doing way wrong, but it would make no difference where they are I don't think Maybe what I need to do is check that being at the resistors instead of being here a higher Then there's a definite, you know, we could split it up There'd be a resistor here and the Zener diode here on the other circuit the same as on this side The resistor would be higher up on the Zener diode below Road you don't like but putting this on there and these are my specs on the meter. They're fine Powering up It's just drawing full current Like it's shorting like it's doing something naughty So I'll have to just keep cracking on it and start recording when I've got something new I feel like at least he's plugged back in The circuit needs back down because that's how it wants to be It's gonna be easy enough to put back together. I just got to find out Let's brag. This is the fun part. This is the bit which is the challenge and this is the bit that I like Be back in a bit We got a little baby here And it's testing this diode as a Unknown part damaged or an old part if I test the other diodes I expect And I expect to see that this day is a worker By that it's indicating it's a worker which is good. So What's this for? This is the gate on On this transistor you pull down to ground And this one isn't gonna go because I should just be able to take this like this And you come up with a diode the same as what we can But it doesn't oh, yeah, but it has a damage that are unknown part So, oh no shit It's not it's working They can't be picking up from there Nope It is as well It does it gives a read out there as well. Okay, that's what I didn't want. I mean, I've got to take these out of the circuit and do it What a pain in the ass. I was hoping I just found a diode That doesn't prove nothing Because I can do the same test from here to here and then to cathode Everything comes up as a diode Which is Never mind. Let's try again Hey guys, uh, just a little bit of a continuation now One of us tested this out when I when I when I built it. I ended up taking it all apart. Well, I'm not all apart I took the um the MOSFET cells to check see if they're okay Uh, because it it didn't work um And it almost it looked like it was shorting And so I thought oh wow, so I obviously damaged the MOSFET or something or of course I lost the damage and it shone up as a short So I took the I took the MOSFETs off. I checked them and I'm fine. So now I check the diodes. I'm fine Resistors I checked the inductors I noticed that this connection here was giving me a bit of resistance. So I re resoldered that I don't know it doesn't look Uh, it looked a little bit more messy than what it did And it still didn't work And so I was a little bit concerned After finishing work today. I'll come back and I noticed looking at it from this angle. I could see that my wire um It was connected, but I think it was it wasn't connected inside quickly because even though But I'm putting this through my good power supply at the minute, which I really don't want to do It's on 12 volt. I'm giving it a maximum of three ounce Uh, and I'm just gonna flick around. But look we got I don't know if you can see that particularly that long There we go, look Nothing special. Nothing to write a hang about Like you say, that's that's that's it's just uh I just wanted to test the circuit see if it works And it does work I know I need a bit more capacitance. They're on the way. That's only a 339 we'll need a 680 really Um But the capacitors are on the way But everything else should be good Everything else should be good and I did run it for a few minutes I did like a bit of a heat test that everything's cold. That's fine Like I said, it's only three amps. My other power supply at the minute is playing up again I've had nothing but problems with it since I first bought it connections and all sorts, but I'll take it apart again a bit Sort a little and I'll come back with some uh With some 10 amp action Or at least, you know, we'll give it a bit more voltage And a bit more A bit more ampage, but just as the uh As my first cvs We're using MOSFETs It works and I'm chuffed to punch absolutely chuffed to punch. It's a little tiny for now, but we'll get there We'll get there. This baby's got enough potential about it to give out some nice arcs. So So, yeah Next video, I love that power supply fixed under them I don't Everything I buy I seem to have to fix Yeah, this is a this is a new thing I got today Uh 4.5 volt to 40 volts and it gives me five volts And two amps on the output maximum But that's brilliant because I've got quite a lot of these things I have to plug in, you know To want to to my phone charger. I got my music player. I've got my my clocks I've got other ones on build and I've got all sorts of stuff I need five amp supply volt And this is great. It's um It's reading the indication off off the supply of nine volts. It's saying It says 8.6 there It says 8.6 there Uh That seems to be quite good I'm just waiting for my phone to drop a bit more on charge and I'll I'll chuck that in and see how quick it to charge my phone up This is 1.5 amps at five volts and this is two amps at five volts So I'm hoping for it a little bit more quickness there. You can actually turn the power off on this Which is pretty awesome And that there Is to that that that button that switches off the entire thing And then this one just turns off the power output So you've still got the power going in And the indication that that power's going in I think which is really really handy Um, but you've just you can just turn off the output going out because that's a little output like indicator. Yeah Fantastic It's been a good day today A couple of these are turned up And this is working No smoke no nothing It's working and I'm much off Cheers watching catching a bit
