Abstract
A power distribution circuit includes a power input in electrical communication with a power input line, a switching circuit electrically connected to the power input line, and an overcurrent protection circuit electrically connected to the power input line. The overcurrent protection circuit includes a discrete silicon controlled rectifier (SCR) circuit, and a pulse qualifier configured and adapted to drive the discrete SCR circuit. A method for controlling a power distribution circuit includes detecting an ON status of at least a switching circuit. A semi-conductor control signal line connects the semi-conductor switch and the voltage command circuit. The method includes detecting an overcurrent status of the switching circuit with an overcurrent detection circuit. The method includes clamping voltage on the semi-conductor control signal line to cause the semi-conductor switch to be turned off.
