@@samueldavies646 both IGBT and MOSFETs work in a ZVS but the IGBT are limited to the lower frequency range. The advantage is they come in higher voltage ratings than MOSFETs. Just got to pay close attention to the spec sheet to make sure you get something that will work for you.
The salt granules on that rod form little peaks for the arc to stick to. Maybe running the salt through a coffee grinder to make it into a fine dust first is the solution.
Try slowly cranking up the input voltage using a variac..... Maybe it can solve the problem of the switches dying. Also what about the inductors for the zvs?? Did you measure them... I have found out that when working with igbt s they don't like lower inductances in a zvs driver... Usually higher inductances work better. 🤨
Your absolutly right, but I built this with the intent to no need a variac. I found that using a small transformer as a seperat gate power source worked well. However you need to use a diode to prevent high voltage from feeding though the secondary of that transformer. Works well now. The problem I am now having I think is related to the inductors. I have fairly large ones, but I need to put more turns in them
Absolutely a sick build I love it! All hand made looks like you even turned the bobbin out of delrin in a lathe, and litz wire for your primary. Sick arcs!
Nice work. I'm wondering: (1) What ferrite core are you using and is it gapped? (2) How many turns does the secondary coil have? (3) What's the power throughput when driving the Jacob's Ladder?
It's a PC40 core off Amazon. I actually broke a few by accident and used them to make the core longer. It is gaped, if I recall correctly 2mm on both sides. I have no idea how many turns are on the secondary.the power draw peaks at I think around 18 or 20amps and 120VAC. I will say I'm having an issue with it. Keeps killing gets when the arc gets big and breaks. I have ideas with whata wrong, but I'm unable to test it at the moment.
That's a beefy old piece'o' kit bruv,80kv with 25amps would leave a nasty stain on the carpet after they scraped what was left of the unsuspecting and oops clumsy operator Wahahaha! Seriously though a brilliant job bud one of the best ladders I've ever seen it could star in some Frankenstein film innit 😎💕🖖
@@theelectronmachines I dont think I can find it, but just look for ferrite cores on amazon and read for PC40 as the core material. Bigger is better. If you only get a few small ones you can tape them together to make the core "thicker".
That’s not 70000 volts. The initial arc distance is a measure of voltage. Not to what it can pull out to. Looks to be maybe 15000. Yes a lot of current. Watch some you tube videos of pole pig transformers 14400. They will pull to several feet. I would rather have voltage not current . I may share a circuit very simple and it’s not a Tesla coil or even resonance to produce extremely high voltages ac . But I know that I will open myself to so many questions. Very good project Andrew. I sure very expensive. Thanks for sharing. I have been a high voltage nut for 60 years. Work In electronics. Took many years of experiment ing to come up with circuit. First time I have ever commented on any video so congrats. You should by very proud.
I did a test with stainless steel balls that are about 2" diameter. I could get it to arc across about 70mm. But this is at high frequency not DC. I'm going to rebuild and test it again because I just love to work on this stuff and test out new things. Do tell of your design!
Well I would rather stir your mind into thinking of concepts for yourself rather dropping a circuit into your lap. But I need to know your depth of electronic knowledge. Because that’s part of the fun right? My background is electrical engineering but I have stayed more on electronic side of it.
@@lyledoherty6980 fair enough. I'm an electrician with very little experiance in electrical engineering. Odds are of you gave me a complicated circut I wouldnt really know what I'm looking at. This ZVS circut is basic and I understand it. But more complicated teslacoil circuts I only understand the basics and dont really know how each component works.
Thanks! It's just your standard ZVS circut but I had to add TVS diodes to it. I just mounted it on a PCB because its alot easier to remove blown transistors when it's just 4 wires and not all the components... and I blew alot of transistors making this work lol. I'm using IHW40N120R5XKSA1in this one. I found they work best with 110 homs on the gates and a seperate gate power supply.
I thought this might interest you, I wouldnt mind seeing what you could come up with in the way of a Jacob's ladder. I think this one will take some beating! 😎💕🖖
It's just your standard ZVS driver. Only difference is I use hight voltage high frequency IGBTs and a seperat gate transformer to power the gates and act as a low power turn on. The way you do this is by rectifying the transformer secondary, obviously. Connect your negative from the transformer to the source for the high voltage for the IGBT/MOSFET. Connect your positive to the gate resistors and to a diode. The diode should be pointing toward the positive of the high voltage. This allows the whole set up to be turned on with lower power based on the out put of the transformer. The diode prevent the high voltage from traveling back through the secondary of the low voltage transformer secondary. This way your not toggling between on and off, just between high and low power.
This is probably the finest zvs- driven high voltage transformer system I have ever seen!
Respect! 🙏 ⚡
Omg please man, i wanna see that in a tesla coil

What FETs do you use?
I do beleive they were:

Gotta keep the frequency low if you want it to work. Under around or under 30kHz

really great looking HV tank and transformer : D ^^
Thanks! It was a pain to build. Many hours of love lol
Dude, that is the cleanest ZVS settup I have ever seen! Very nice! Also great output.
Thanks!

PC 40 core I do believe

@@lyledoherty6980 just because he has that ~15mm gap doesn't mean it's 15kV. it does look like around 70kV from the way the arcs behave.
I whould say the arc starts about at 3cm and goes up so its 30-90kv

Hello, impressive work! Could you tell me what liquid you use to submerge the high voltage winding? Or your business name? Thank you very much.
That is sweet. What would you charge for one of those flyback enclosed in plexiglass and oil?
Lovely build, gorgeous ladder.
How many mAmp is high voltage side and how many wires in primarily winding for litz ones approximately?
Impressive build! You should try a full bridge next.
Wow, thats just incredible awesome. If i could i would definitely also build one myself :D
One of the most silent ZVS Jacobs ladders I've ever heard/seen. Nice work!
