555 ZVS DRIVER
Since I followed your component list in the schematic to make this circuit I feel I should ask first before I enable adverts since you came up with what components to use. Your timer configuration did not produce a square wave at the output and conducted all the time instead. March 18, at September 16, at Which pin in the gate, drain and source? The information has been extremely helpful for me! Heres the full setup:

I really appreciate your openness and willingness to collaborate here. October 9, at I am wanting to create a variable ozone generator circuit, so looks like ZVS is not a good way to go about it.
Make sure you use a mosfet and not a bipolar junction transistor, the symbol in the datasheet should resemble the one in the schematic. It can be a monster if done right! Since flyback transformers use a ferrite core they need vastly different operating 55 than an iron cored mains transformer.
This is what I hate the most. More on this here. The first two drivers on this page drive the flyback in flyback mode, while the last two use push-pull topologies.
Seen some questions here. If you can give me a help I appreciate it thanks pedro. It is set to run between 17 — 50 kHz. svs
Hope my info helps! Also, I see five volts on your meters — not enough at all to drive the chip, lest the gate.
Gracias y saludos desde Paraguay. Therefore, when i was searching for a more robust flyback driver in order to use it as my tesla coil power supply afterwards, i realized that zero voltage switching ZVS flyback driver can give high voltage without heating the MOSFET too much sometimes even none! Same circuit as yours, at 40V, I busted a 3.
The max voltage is 50V, due to flyback spikes. I always have one problem, the power transistors keep burning out. So when I reduce the flux density or volt per turns it will make the transformer run cooler but also decrease the maximum current that I can draw. So maybe i can use these diodes to create Villard cascade and some juice glass bottles for the high voltage capacitors.
Zvx can be very time consuming to design zsv an circuit but the effect can overcome the time zvd in it, a lot of DIY community member will benefit from such protection circuit.
Hey Dan Do not use high voltage as a weapon or defense system, unless you buy a certified system. A golden rule on those things, is oversize.
Pictures Spark at 5v.

Flyback driver #2: NE555 quasi-resonant
Use a hair drier, or a gas cooker to liquify grams of paraffin wax candles, please use an white wax so it look good! The mass of the paraffin could be changed. This is what I think causes half of your problems. It worked great for a little while until it just 55. I have tried building on myself with flip-flops and gate drivers, it worked but was very unstable and in the zvx it killed my MOSFETs.
This is why it might oscillate, but not conduct any current worth mentioning. The ground pin can be found by finding the pin the HV arcs to the most.
Is it important how I connect my primary in case of this NE quasi-resonant?
