Abstract
A circuit for operating an arc discharge flash lamp that is directly coupled across an alternating current (AC) source. The lamp is ignited by a high voltage pulse generated by a trigger circuit energized by the AC source. A voltage multiplier, such as a doubler circuit, is connected across the flash lamp for increasing the voltage across the lamp above that provided by the AC source, thereby facilitating starting of the lamp by the trigger circuit.
