When switching control signals of self-excited semiconductor devices (G1, G2) from OFF-control to ON-control, a control circuit controls the self-excited semiconductor device (G1) to be ON after a lapse of a turn-ON time (2 × ”t) from when a control voltage is applied to the self-excited semiconductor device (G2). When switching the control signals of the self-excited semiconductor devices (G1, G2) from ON-control to OFF-control, the control circuit controls the control signal of the self-excited semiconductor device (G2) to be OFF after a lapse of a turn-OFF time (2 × ”t) from when the control voltage is applied to the self-excited semiconductor device (G1). |
