Bare&Basic ZVS Circuits of all shapes and sizes.

This is a video how how to make many forms of ZVS ( Zero Voltage Switching ) with many common components. This is not a direct tutorial but a guide to real life design and troubleshooting.
Some things I stated a little strange a few thing stated wrong, some mistakes are present. It's almost like I am human too.

This is a LONG video and had a lot of verbal and observational information in it, but if you struggle to make your own ZVS I do very much hope this video helps you.

There will be many circuits made in this video for both step up and step down transformers as well as different wattage set ups as well.

Another thing to note is that I say transformers with a single primary coil are for full bridge configurations, while yes that is the way you run a transformer like that there are many other set ups that use a single wire primary transformers such as single mosfet switch mode PSUs and pulse transformers.

You had me at SMT ZVS..I laughed so hard at the device's testicular fortitude! Thank you sir. You demonstrate remarkable knowledge in a well spoken and accessible way, I appreciate that you take the time to share this with us - well done!

As you probebly knew, I have been working on making my very own plasma pen; and this was a huge help, thank you

[daveking]

Man I'm sure glad I found your channel, you are a great instructor. As a 60 year old mechanic I find myself lost on the ECM's in my Dodge trucks, which the 1991 is about to be modified back to a carburetor and a points distributor like the earlier models.

With the knowledge I've learned in this one video, I will postpone the swap until I see if I can find the problem with the brain. Thank you brother for your patience and willingness to help others, it's very much appreciated. Subbed.

A friend gave me some random stuff a while back and in it was one of those little high frequency transformers. It had a center tapped bifilar primary so when I saw it had a decent arc from feeding half of the primary a square wave I tried just wiring it up as a blocking oscillator and it gave me an amazing arc from something around 5 watts. It was surprising similar input and output compared to what I got using the frequency and on time I ended up liking the most from the square wave generator so it must have been a fairly low duty cycle still able to output the burning plasma. The arc was way longer than it should have been, something close to an inch and I was going to make a battery arc lighter from it but tried 'potting' it with gorilla wood glue and it ruined the secondary. Similar transformers I pulled from LCD monitors wouldn't perform the same. Been trying to get into flybacks again recently and I always think of that little transformer.. tape was gone too along with the part number. I'll def be absorbing what I can from this video over the next week or so I've just been slacking on scrounging for some 12v zeners.

There is something hypnotic about watching the mosfet whisperer! Seriously, great video!

Hi, I saw you in join the technicians a few years ago. Glad I stumbled onto your channel. I have a love hate relationship with these zvs drivers lol.

[HighVoltageMadness]

Thanks man I finally was able to make a zvs driver that doesn't blow up! Much THANKS!

[mightymagnum]

At 51 minutes you say "they're gonna be going in opposite ways" but they look like they're a constant direction of rotation, with the centre tap being just being an interruption, in a continuously spiral helix. Am I misinterpreting what you say, or am I misinterpreting what I am looking at? Thanks. This is the best video I have found on explaining the working of a ZVS. The smoke tests really do help clarify things. Great job.

[SIKHGT]

I love zvs circuits and arcs, ,, you are hero bro ....great work ....I will try it

[cuf_]

Tank you buddy! I got my first zvs thanks to you. I improved the circuit a bit so i could use it as a induction heater. Im a big sub!

[eliastimmons]

Thank you so much for this video, of course I haven't watched it yet, but I will as soon as I have time to. Looking forward to it!

[KraussEMUS]

Thank you for the wonderful video! I especially liked the smallest ZVS supply that you made!

[EddieBedwell]

Thank you thank you thank you. I am a tinker and a lover of Tesla, you are the best that I have found. Thank you thank . I have accidentally found a circuit. I’d love to share with you.

[lonnymoore]

your awesome . love seeing you work your brain seems to go like mine wen it comes too electronics . everywhere all at once .

[stephtronix]

Great video thank you, now I know how to tune my zvs circuit!

[danielfoster]

Nice work. Jeremiah is a great soul. He shared my gravinductor here on YouTube.

[JotticunChapter]

I ordered a Transformer simular to the one you used in the plasma pen video, it just was about 16 times smaller but looked identical!

[steeringelectricity]

@ about 5:30 - Should you have said "Negative at source PULLS DOWN the other fet and turns it off"? I'm completely thrown off by you saying a negative current flows against the cathode of a diode. I'm super new to this hobby so I may be missing something obvious but I don't get the negative current flowing reverse bias THROUGH a diode. Maybe electrons flowing through that way? Or most likely just could have misunderstood.

[richlong]

Can you do a deep dive into the plasma candle circuit ? I can’t find anything close to adequate regarding this topic .? Fantastic work on this one by the way 🙏

Cheers mate, as raw as this video is, it's quite educational. Also, glad I'm not the only that struggles with solder joins. Heh. I hate watching these guys that tap their soldering iron on the joints once and get instant joins..
