Abstract
A power converting apparatus comprising a group of semiconductor switches and DC terminals electrically connected to the group of semiconductor switches, in which a clamping circuit is connected to the semiconductor switches or the DC terminals. Otherwise, a diode having a wide band gap is connected in parallel with a snubber diode or a snubber capacitor of a snubber circuit connected in parallel with the semiconductor switches. With such arrangement, an overvoltage or oscillating voltage impressed on the semiconductor switches is suppressed.
