Abstract
An assembly structure of a self-turn-off switching device and a snubber circuit connected in parallel with the self-turn-off switching device. The snubber circuit is composed of at least a series circuit of a snubber diode and a snubber capacitor. The assembly structure includes the self-turn-off switching device, the snubber diode and the snubber capacitor. The assembly structure also includes a conductive heat sink on which the self-turn-off switching device is mounted at a first surface thereof and the snubber diode is mounted at a first surface thereof, for cooling the self-turn-off switching device and the snubber diode and for connecting the first surfaces of the self-turn-off switching device and said snubber diode. The assembly structure further includes a first conductor on which the snubber diode is mounted at a second surface thereof for connecting the second surface of the snubber diode and a first terminal of the snubber capacitor, a second conductor positioned in parallel with the first conductor for connecting a second terminal of the snubber capacitor and a second surface of the self-turn-off switching device, and an insulating spacer positioned between the first an…
