November 1, at Or, run it on low voltage input with a kilovoltmeter in the output. As you can imagine, the arcs were insane! Can you upload to youtube detail video circuit of new prototype driver.
Flyback Transformer Drivers
The ratings of these body diodes can be inferior and thus a faster external diode is used. It means that you disconnect the primary connection from the supply that provides Vcc to the oscillator NE pin 8 and use a different supply for the primary zgs, sharing the same ground with the supply that provides power to the NE September 16, at I did find some errors I made though.
The internal body diode is a by product when transistors are manufactured.
Kalau tk silap saya, cas elektrik ni dipengaruhi oleh cas ion betulkan saya kalau silap. I am still getting little arc, but the current now is very low,now i am going to find the resonant frequency xD, thanks!!
Flyback driver #2: NE555 quasi-resonant
Your projects is really nice, you did a good job. The kind of arc is quite different between the 2N inverter and the Mazilli ones. March 19, at I want to point out another important matter with this driver: Remove old primaries and secondaries, wind a new primary and secondary for each core they must all be the same and then wire them in series and finally put all the assembly into oil.
Your xvs cap should be suited for between 40kHz and kHzjust keep an eye on the tank voltage.

Soive got myself interested in the ZVS driver againand dig out my old build. Mazilli ZVS flyback driver Introduction The Mazilli ZVS flyback driver is well-known throughout the high voltage community for its simplicity and ability to deliver kV at high currents for a flyback transformer.
When you say main ground you mean the socket ground?
Note that if your tank voltage is low and current draw is high, you either need more primary turns its basically short circuiting or smaller tank cap between 1uF and 0. Hy Jozef First of all, thank you very very much for yours answers, i reworked my circuit because it was not like yours and here is the link to the schematics and photos.
I would not omit the zener diodes, there can still be switching spikes which are voltage transients that are high enough voltage and have enough energy to damage the gate of the MOSFET.
Flyback driver #2: NE quasi-resonant – BOGIN, JR.
Notice how everyone uses a mask when welding? Sign up using Facebook. I do have a disclaimer up above, but I think I would not want to hear you have been killed by one of my zvx. Post as a guest Name. A transistor will only conduct as much current as you also feed its base times the amplification ratio of it.
Other than things above there is no change from the orginal circuit. Basically just check that everything is wired correctly, if it is, check that all the parts are functioning.
Some blow up very ramdomly.
No, only one, but i tried with another to check if the problem was IRFP. But I guess the voltage tolerance is derated for higher frequencies. Would it be any problem if in place of the ohm resistor was one of ohms? Xvs that the switches in a ZVS driver sees pi 3,14 x supply voltage.
