ABSTRACT:
An arc lamp igniter circuit (10) employs a resonant inverter circuit (16) to convert low-voltage DC to a relatively high-voltage, 80 kilohertz sinusoidal AC voltage that is rectified and voltage-doubled (42, 44, 46) to about 2,500 volts DC for repetitively charging an igniter capacitor (50) until it discharges through a spark gap (58) and a primary winding (54) of a compact, low-mass igniter transformer (52). A secondary winding (56) of the igniter transformer provides repetitive 20 kilovolt pulses, which are sufficient to ionize a metal halide arc lamp (14), causing it to ignite and produce intense illumination.
