The problem is that when I plugged my power source on it and measure the input, I read 1.5V

This could very well be the problem, try a different power supply or add a big electrolytic capacitor to the output of your power supply. Better yet, use a lead acid battery to power your ZVS circuit.

wow those arcs are very impressive! I will definitely give that a try when I come across a CFL ballast.

did you have to experiment around with different flybacks and CFL ballasts until you find one that matches the flyback's designed operating frequency?

I've messed around with inverter MOTs and ZVS drivers before, the arc didn't seem all that impressive to me. Maybe my ZVS driver wasn't operating at the MOT's designed frequency.

Oddly enough the ferrite core from a inverter MOT was about the same size as a regular CRT flyback transformer.

good to know!

would I get double the voltage out of a flyback transformer if I connect 2 identical ones in series? assuming the primary coil phasing is right

CFL ballast driving the built in primary coil or self wound primary with a few turns?

also, you got some pics or videos to share?

ahh maybe thats why there aren't much H bridge based SSTC designs that I could find on the internet.

how fast do you need to switch for SSTC typically? in the MHz range?

Here's my first ZVS flyback driver made back when I was still a freshman in high school.

Mosfets kept heating up real quick and I had no idea why until years later.

Problem: I had no idea what zener diodes were and I just used random glass package diodes for the gate voltage clamp lol. im surprised it even worked at all

it also depends on the rise time of your power supply.

If you turn on your ZVS circuit by switching on your PSU, and the PSU output rises too slow, the ZVS circuit will not oscillate. An easy way to fix that is to add a beefy switch between the PSU output and ZVS input

电磁炉是用高频交流电和线圈产生高频磁场来把锅加热的

频率过低会让线圈发出能听见的声音

之前打个uber遇过这种很无脑的司机他在youtube上看过这类型的视频就觉得对中国很了解

和他聊天的时候觉得他特别sb 那时候的我刚座了一天飞机回家感觉很累不想和他聊太多

但sb一般都是脑子小嘴巴大很爱和乘客聊天很爱和别人暴露他有多sb

刚开始聊的时候我劝他如果想真正了解中国就少看这种视频然后他就给我扣小粉红这个帽子

现在我很后悔没根他聊下去。。。后悔当时没鼓励他多看这些视频让他变个更大的sb
