Im making a diy induction heater but the problem Is despite making things hot on its business end coil mosfets are getting heated up with a huge voltage drop. I have checked for any short in the circuit haven't found any.
Circuit is
Waveform at the gate terminal ( both similar)
I' using 12v and the voltage drops to about 4.6v with a current of 0.7A.
This circuit uses zero voltage switching to oscillate, i've read that. Also author says that the gate resistor should be small but not to small that when mosfet is on and other off by pulling down one resistor it should not create a short in power supply. I think that is what happening here.
