MAZZILLI ZVS FLYBACK DRIVER
The only problem I have had with it so far is that it has a tendency to destroy every capacitor I use with it after a while.
I found another random film cap in an ATX mazzilli zvs flyback supply a while ago with pretty good specs so I tried it. It worked surprisingly well for about a week before it too over heated and failed.
Once I tried it unloaded, but with the leads from mazzilli zvs flyback secondary about 2mm apart to form a spark gap in case something happened. Something did happen. After that it all it did was get hot.

I checked the transformer and there was continuity between the primary and secondary. After rewinding it and testing it at both 24V and 12V, loaded with the uF cap bank, I've still got the same mazzilli zvs flyback.
Everything is getting hot, and the caps don't charge. Smarter versions like the Kaizer Power Electronics 2n flyback driver add a capacitor and diode to protect the transistor.

As shown, multiple 2n transistors can be run in parallel to spread the load and dissipative snubbers can be added to protect the transistors from voltage spikes. I made a very simple power supply from a transformer from my local mazzilli zvs flyback swap meet. To have a visual indicator and also a mazzilli zvs flyback resistor, I used a microwave oven lamp.

The lamp glows when the power supply is mazzilli zvs flyback and also bleeds away the chare from the two large filter capacitors. Bleeders are needed for safety reasons. December 26, In Interesting Pages.
Craig February 10, Adam February 14, The one featured here resonates at 75 kilocycles or thereabouts. Andrew February 17, Adam February 17, Unfortunately no.

Andrew July 8, Can I change the frequency on this driver? If yes what should I do?
Henry O'Keeffe June 28, Dare Diamond January 12, If your supply is working at mains frequency, you will need some hefty filtration caps; mazzilli zvs flyback least 10 to 15 mF is recommended to get rid of that mains hum. Also do not forget to heatsink the rectifier. Now, this driver is really good when it comes to efficiency and output current in comparision with other topologies, however, it is quite difficult to obtain more than 40 kilovolts out of a single DST flyback without increasing input voltage, thus stressing the components more, or without an external high voltage multiplier.

And use a proper power supply. AhmadM11 4 years ago on Introduction. Finally I made it!
