Abstract
An electric power conversion device includes: a switching element; a collector side wiring connected to a collector side of the switching element; an emitter side wiring connected to an emitter side of the switching element; a detection circuitry configured to detect an induction voltage generated in the collector side wiring or the emitter side wiring when a current flows through the collector side wiring or the emitter side wiring; and a comparison circuitry configured to compare the induction voltage detected by the detection circuitry and a predetermined threshold voltage determined in advance to each other.
