A power converter apparatus has a solid-state switching device 11 for cutting off a current flowing from a DC power supply 1 to a bridge circuit 2 when reverse-biasing thyristors in the bridge circuit 2, and an inductance element 12 and an auxiliary solid-state switching device 13 connected in series between positive and negative DC lines interconnecting the DC power supply 1 and the bridge circuit 2 through the solid-state switching device 11. A magnetic energy is stored in the inductance element 12 during an interval of time in which the solid-state switching device 11 and the auxiliary solid-state switching device 13 are rendered conductive. The magnetic energy is discharged to reverse-bias the thyristors.
