摘要 PROBLEM TO BE SOLVED: To reduce conduction loss of a circuit while reducing noise in an existing conversion circuit.SOLUTION: A circuit device comprises an IGBT and free-wheel diodes connected, in parallel, to the IGBT. Each free-wheel diode is configured by connecting, in parallel, a Schottky barrier diode and a silicon PiN diode that are composed of semiconductor material having a larger band gap than silicon as base material. The Schottky barrier diode and the silicon PiN diode are individual chips.
