Abstract

A power supply that converts an unregulated DC voltage source to a regulated AC power source suitable for energizing an electroluminescent panel. The DC voltage source powers a DC-to-AC inverter to generate an AC output. A feedback circuit monitors the AC output and compensates for any changes in amplitude that arise due to fluctuations in the DC input voltage. A single reference voltage is used to both selectively energize and deenergize the circuit and to control the amplitude of the AC output.
