zener diodes in zvs driver, what voltage?
alf, Wed Jul 20 2011, 10:56AMhey,
im gonna make the zvs circuit, im going to use uzzors seperate supply circuit, the oscillator will be at 12v, and the power section will be 12, 24, or 36v, i am gonna use irfp250n mosfets, what voltage, and power should the zeners be?
thanks. Alf.

Theoretically you don't need any zeners, for safety I would use 15V 1-2W zeners.

I thought that zener diodes are what switch the gates? On my ZVS I use 1n4744a (15v about 1W) zeners and have input 56 volts into the ZVS driver with standard 470 ohm resistors.

Nope, what switches the gates are the fast feedback diodes.
