Abstract
In a power converter including at least one bridge circuit configured to have upper and lower arms in which a first power semiconductor device and a second power semiconductor device are connected in series, a first gate driving circuit that supplies a charge to the first power semiconductor device of an upper arm to drive the first power semiconductor device monitors a voltage developed by an output inductor between a connection end between the first power semiconductor device and the second power semiconductor device and a load, and performs control to protect the first power semiconductor device based on a value of the monitored voltage.
