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 5):
The snubber circuit of  claim 1 , wherein the static snubber unit comprises at least one static voltage sharing resistor.
