Abstract

See full text

A pre-charge circuit is provided for an electromechanical relay having a coil and relay contacts. The pre-charge circuit includes a semiconductor switch configured to be electrically connected across the relay contacts of the electromechanical relay. The pre-charge circuit includes a resistor configured to be electrically connected in series with the semiconductor switch between the coil and the relay contacts of the electromechanical relay. The pre-charge circuit includes a driver configured to be electrically connected between the coil of the electromechanical relay and the semiconductor switch such that the driver is configured to power operation of the semiconductor switch. The semiconductor switch is configured to pre-charge a capacitor of a load of the electromechanical relay with electrical current through the resistor for limiting in-rush electrical current supplied to the relay contacts of the electromechanical relay.
