ABSTRACT:
Respective terminals and connecting means provided between respective terminals are arranged such that both a current path of a first current extending from an alternating current output terminal 7 (AC) to a negative terminal N of a capacitor 10 via a switching device SW2 and a current path of a second current extending from the alternating current output terminal 7 (AC) to a positive terminal P of the capacitor 10 via a switching device SW1 are provided to construct round current paths whose forward and backward current paths are positioned mutually in a close vicinity respectively. As a result, a snubber circuit can be omitted, and also a power converter device which has reduced size, lower loss, lower cost, and higher reliability can be achieved.
