Abstract
The inverter comprises a plurality of branch circuits connected across a DC source. Each branch circuit includes a pair of main controlled semiconductor switching elements, a diode and a smoothing reactor which are connected between the pair of main controlled semiconductor switching elements. A commutating circuit including a commutating capacitor, a commutating reactor and an auxiliary reverse conduction type controlled semiconductor switching element is connected in parallel with each main controlled semiconductor switching element. A pair of circulating diodes are provided for each branch circuit and connected between respective commutating capacitors thereof and the positive and negative sides of the DC source.
