Abstract: Cooling arrangements are disclosed for solid state circuit breakers. In one arrangement, a MOV is disposed between two pulsating heat pipes. An IGCT is disposed on the other side of each pulsating heat pipe away from the MOV. In another arrangement, a bus bar is integral with a heat spreader disposed between a pulsating heat pipe and an IGCT.

Abstract: A surge arrester system includes a surge arrester, and an active cooling system having a cooling interface in contact with the surge arrester and operative to transfer heat from the surge arrester. The active cooling system includes a forced convection apparatus operative to provide forced convection cooling. A circuit breaker system includes a power semiconductor switch and an active cooling system constructed to cool the power semiconductor switch. The active cooling system includes a forced convection apparatus configured to provide forced convection cooling. The power semiconductor switch is in contact with the active cooling system. A surge arrester is disposed adjacent to and in contact with the active cooling system. The active cooling system includes a cooling interface constructed for contact with the surge arrester and operative to provide cooling to the surge arrester. The power semiconductor switch and the surge arrester dissipate power alternatively.

Abstract: 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.
