Abstract
A semiconductor device includes: reverse conducting switching elements-in each of which a diode element and a switching element are arranged in parallel on a single semiconductor substrate; a driver applying a gate voltage to a plurality of gate electrodes in the reverse conducting switching elements; and a mode determination unit determining whether a forward conduction mode in which a current mainly flows through the switching element or a reverse conduction mode in which the current flows through the diode element is being operated.
