ABSTRACT:
A solid-state switch has a plurality of gate turn-off thyristors connected in the rungs of a ladder circuit and a plurality of diodes connected in the side rails of the ladder circuit. The anode of the first gate turn-off thyristor is connected to the cathodes of the first and second diodes, the cathode of the first gate turn-off thyristor is connected to the anodes of the third and fourth diodes. The cathode of the second gate turn-off thyristor is connected to the anode of the second diode and the anode of the fifth diode, the anode of the second gate turn-off thyristor is connected to the cathode of the fourth diode and the cathode of the sixth diode. The anode of the first diode and the cathode of the third diode are connected together at a common point, which is selected to be one terminal of the switch. The cathode of the fifth diode and the anode of the sixth diode or the anode of one and the cathode of the other one of the last two diodes of the ladder circuit are connected together at a common point, which is selected to be the other terminal of the switch.
