Abstract:
The present disclosure relates to a snubber circuit which comprises a static snubber unit, connected in parallel with the switch, for balancing a static voltage sharing across a switch when the switch is in a state of turn-on or turn-off; and a dynamic snubber unit for balance a dynamic voltage sharing across the switch when the switch is in a process of turn-on or turn-off, comprising a dynamic voltage sharing capacitor connected in parallel with the switch and having a relationship between a capacitance and a voltage of the dynamic voltage sharing capacitor; and a controller for controlling the capacitance of the dynamic voltage sharing capacitor to be in a predetermined working area of capacitance rising while the voltage across the switch is increasing. The present disclosure also relates to a power semiconductor device.

Claim (Index 3):
The snubber circuit of  claim 1 , wherein the controller comprises:\n a receiver for receiving a voltage across the switch; a calculator for determining the capacitance of the dynamic voltage sharing capacitor based on the received voltage across the switch from the relationship between the capacitance and the voltage of the dynamic voltage sharing capacitor; and a regulator for regulating a gate driving signal provided to the switch so that the capacitance of the dynamic voltage sharing capacitor is in the predetermined working area when the determined capacitance of the dynamic voltage sharing capacitor exceeds the predetermined working area.
