Abstract
A power interrupter device includes a solid-state bidirectional switch and control circuitry to control the solid-state bidirectional switch. The bidirectional switch is connected between input and output terminals of the power interrupter device. The control circuitry includes driver circuitry and fault detection circuitry. The driver circuitry generates a regulated direct current (DC) voltage using current drawn from an input power source applied to the input terminal and applies the regulated DC voltage to a control input of the bidirectional switch. The fault detection circuitry is configured to sense a level of load current flowing in an electrical path between the input and output terminals, to detect an occurrence of a fault condition based on the sensed load current level, and to short the control input of the bidirectional switch to place the bidirectional switch in a switched-off state, in response to detecting the occurrence of a fault condition.
