Two years ago, I built an inverter from DC to AC 12 to 220 using 12 * 2N3055 and I used 4047 for the Oscilator then,
Now I want to use Mosfet transistors instead of 2N3055 which they are IRFZ44 with the oscilator 4047 then when I connect the + of the 4047 circuit the two mosfet transistors are explode, would you please let me know what's the problem?
please post your circuit..... because i believe there is a problem due to the current drive.... if you post the circuit then it would be easy to find the problem....

the opamp is sourcing and sinking current and this is what damages the MOSFETs.... I think using BJT is a better idea... maybe you can use a cap between your MOSFETs gate and ground but that would slow your circuit very badly....

I am busy with the same project and also using the IRFZ44. Lucky when searching I got to this... Please let me know if you have a circuit that can drive the mosfet without problems. How many mosfets do you have in parallel?
