I am using CAB320M17XM3. I had applied applied a DC voltage of 800 V across pin 3 and 2. But the gate to source signal to none of the device was applied. In this scenario the half bridge is dead short circuited.

Could you please help me understand as to why this happened?

    Hi Aradhya,

    Thank you for reaching out. It might be the case that the device is ON (CISS charged) or it could have been turned on via the miller capacitance. Please make sure the device Gate-Source is kept shorted or held at -4 V to make sure it is turned off.

    Thanks,
