A snubber circuit has a voltage detection circuit which detects that a voltage between first and second terminals exceeds a predetermined voltage, a protection circuit which performs control to prevent an overvoltage between the first and second terminals when the voltage detection circuit detects that the voltage between the first and second terminals exceeds the predetermined voltage, and a voltage control circuit which bypasses a portion of a main current flowing between the first and second terminals to the protection circuit when the voltage detection circuit detects that the voltage between the first and second terminals exceeds the predetermined voltage.
