My mosfet open circuit voltage- 400 volts.

Switching frequency-70000

I am not using Snubber CIRCUIT to eliminate ringing .Are there any other options to eliminate ringing.Now i am using an active clamp circuit(tvs diode between Gate and Drain).I don't want to waste power at snubber circuit.Am i correct with TVS Diode?Please suggest me how to deal with this ringing.

Hi Annapurna,

With your case, that depends on the application or to your designed system, since some TVS are limited to DC in which you need to have bidirectional TVS to use it in AC. You need to consider if your system requires dissipation or not. You may provide additional details about that circuit or system, so we can help you more.

God Bless.

Best,
Neil
