ABSTRACT:
DC operated power supplies for electroluminescent lamps are self-inhibited from further oscillations and thus are current limited in the event that a failure occurs in an EL lamp which results in the EL lamp being shorted. Single ended and push/pull transformer power supplies are disclosed, and a transformerless solid state power supply is disclosed utilizing a voltage multiplier, and an inhibitor circuit at the output of the voltage multiplier responsive to substantial voltage drop upon the occurrence of a shorting of the EL lamp, to inhibit further oscillations and operations of the circuit.
