Abstract
A power semiconductor module includes an element pair formed by connecting, in anti-parallel to each other, an IGBT and an FWD group in which an FWD, a voltage drop characteristic of which during conduction has a negative temperature coefficient, and an FED, a voltage drop characteristic of which during conduction has a positive temperature coefficient, are connected in series and an element pair formed by connecting, in anti-parallel to each other, an IGBT and an FWD group in which a FWD, a voltage drop characteristic of which during conduction has a negative temperature coefficient, and an FWD, a voltage drop characteristic of which during conduction has a positive temperature coefficient, are connected in series. The element pairs are connected in parallel.
