Hi Friends,
I have tried gate resistance 4.7 and 10 Ohms driving voltage 12V. This circuit working normally bellow 8Amps, Crossing 8Amps the diode D1 and the input capacitor C2 are heating up. Above 10 Amps the Mosfet , diode and input capacitor are heating up and after sometime its blow up. I have designed this for drive 20A load.
