Systems, methods, techniques and apparatuses of power switches are disclosed. One embodiment is a power switch comprising a first reverse blocking integrated gate-commutated thyristor (RB-IGCT); a second RB-IGCT coupled in an antiparallel configuration with the first RB-IGCT; a transient voltage suppressor coupled in parallel with the first RB-IGCT and the second RB-IGCT; and a controller. The controller is structured to determine a direction of a current flowing through the power switch, determine a magnitude of the current flowing through the power switch exceeds a threshold, and turn off the one of the first RB-IGCT and the second RB-IGCT receiving a current flowing in a reverse direction in response to determining the magnitude of the current flowing through the power switch exceeds the threshold.
