ABSTRACT:
A power supply for a low-loss sinusoidal drive system is disclosed for powering thin-film electroluminescent displays (TFEL). A DC power source is coupled through a DC-to-AC inverter for driving an LC resonant tank circuit which is used to produce a sinusoidal supply voltage. A sinusoidal supply voltage is then coupled to produce a sinusoidal backplane driving voltage which, in cooperation with a logic circuit, controls the drive for selectively energizing segments of the TFEL display. The power supply is constructed to synchronize itself with the tank circuit in such a manner that sufficient power is added to make up for the tank losses and allow the tank to ring with a sustained constant voltage level. This produces an efficient sinusoidal power source which can accommodate varying loads and is operable at low voltage levels independent of output voltage requirements.
