MAZZILLI ZVS FLYBACK DRIVER DOWNLOAD

Hi lahor It can properly run down to some kHz, not that I have tested it, but its an assumption based on time needed to switch state. I applied five-minute epoxy to the flyback several times to avoid arcing, and eventually ended up cutting off all the unnecessary pins and covering the whole bottom in epoxy. If you get poor switching then redesign the drive circuit. I started out at 12 volts, and no problem, but when I added 24 volts, the same thing happened as when I added 36 volts previously. It made a big difference, much hotter, thicker and longer arcs. I modified the work coil , it worked extremely well, and then my microwave cap exploded XD. Currently i have 3 of these mosfet but i will buy more soon.

Hi everybody, I not work in physics but interested in flyback circuit.

Robert M Rutledge says: Congratulations, that mazxilli a fine output you have there, not too current heavy, so might be useful for some high voltage applications that does not require a large current.

As for the transformer there is no overcurrent protection so when one got fried the other also got fried. Both ways, you still need good insulating material, as you want to reduce corona losses — even if you made the full wave multipliers, as illustrated in the first schematics. Hope your mazilli lives up to the effort you put into itit is the most robust driver i can think of for its simplicity.

Proudly powered by WordPress. Hi Dylan, Many thanks for your comments. I really don’t think I mazzillli drawing 30 amps, but I guess if they failed, it did. Leave a Reply Cancel reply Your email address will not be published. But its just not enough!!!

Adding a higher voltage should effect the frequencybecause it will be charging the tank cap faster than the lower voltage would. January 7, at The FETs were also fine with another flyback, which died due to arcing.

You could increase the capacitor size up to about uF. In the past I tried using a bridge and Oscope, but that has not worked well for me.

Did you check the battery voltage when you are drawing arcs? The flyback I have choosen puts out a strong arc with my driver. Fewer primary turns will give you a bigger output, but also increase primary current and vice versa for more primary turns.

It made fljback big difference, much hotter, thicker and longer arcs. I believe my problem had been a short in the secondary winding — there seems no way one can test for this easily — I would have thought that this would have given rise to excessive current draw but mazzillk did not happen with the Mazilli although it did with the 2N driver set up — although I have found that the latter always heats up and needs large heatsinks even under normal working conditions.

Any idea what year he came up with it?

I am under the impression my input voltage is flygack high, but im also unsure of what freq the tank needs to be for more heating power. Current draw is less than 1 amp when no arc; goes up to 4 amps with arc after touching HV wires.

But as you said, easier and cheaper with lower HV in and a couple more stages.

More turns on the secondary side will also increase your voltage output. Did you replace the melted inductor or just attempt a fix? I can also salvage the heatsink and cooling fan from it. What did you power the circuit off? Take a look at the page about the Royer induction heater where this same circuit is described more in detail about ratings and some measurements.
