Multiflash operating circuit directly coupled to AC source

摘要

A circuit for efficiently operating two arc discharge flashlamps. The lamps are series connected and directly coupled through series circuitry across an alternating current (AC) source. A storage capacitor is connected between the junction of the lamps and one terminal of the source. Trigger pulses are alternately applied to the lamps so that the storage capacitor is charged when one lamp flashes and discharged when the other lamp flashes. RC timing circuits energized by the AC source control the time of pulsed ignition of respective lamps with respect to the phase of the AC waveform of the source.
