Driverless DRSSTC Interruption

[ARCreator]

Hello, so i have built a Driverless drsstc and the driver works fine but my interrupter FET that switchws the source of the main FETs, is there an other way to switch the circuit without high current switching? I have no NPN transistors and fets that could handle the high peak power draw. Should I seitch the bias resistor going to the fets with a relay? Ik it will die after a while but i want a quick solution till I get a proper fet. I will try to link an image of the schematics.

Do you have a schematic for this circuit? We will be better able to help if you provide a schematic, and other relevant info about your coil.  I've never heard of a driverless DRSSTC, other than the classic HFDRSSTC circuit, which is typically not called a DRSSTC.

You should just be able to pull the mosfet gates to ground with another mosfet to interrupt the push pull Class E circuit. Very similar to the Tefatronix sstc4 circuit. Although maybe there’s a reason why all the push pull class E/driverless DRSSTC circuits use a mosfet to pull the sources to ground. Maybe over voltage protection? Default off instead of default on? Weird startup transients?
