Abstract

See full text

The present disclosure provides controllers for power distribution network circuit interrupting devices and provides electronic control circuits for inclusion in such controllers. The electronic control circuit has a boost circuit, a capacitor storage unit and a pulse width modulator control circuit. The boost circuit boosts an input voltage to a value to supply sufficient energy to a protective relay solenoid to energize the solenoid. The capacitor storage unit stores the boosted voltage from the boost circuit. The pulse width modulator control circuit is responsive to a control and enable circuit to selectively enable energy from the capacitor to energize the one or more protective relays in power distribution system circuit interrupting device.
