Hi
I make a H bridge circuit with IR2110 driver. It works with 24 Volt but when I connect it to 310 Volt (that makes with 220 Volt AC) it does not work. in fact high and low side mosfets gate source voltage set to 0.026 Volt and when I change duty cycle it(gate source voltage) does not change. my schematic attached here.
PWM Frequency = 20KHz
Mosfet = IRFP460A
Please Help me.
Thank you
