Abstract
In an inverter apparatus of the type comprising a plurality of thyristors connected between a DC source and an AC load, a control circuit for sequentially turning ON and OFF the thyristors according to a predetermined sequence, and a reverse bias circuit including a pair of power transistors respectively connected in series with the DC source and ON.sup.. OFF controlled by the control circuit for applying a reverse bias to the thyristors to effect simultaneous commutation thereof, and a pair of diodes connected across the DC source, there are provided a second thyristor connected between the plurality of thyristors and the power transistors and turned ON at the time of commutation of the plurality of thyristors by the control circuit and a reactor connected in parallel with the second thyristor.
