200_W_SEC_SYMMETRICAL_INVERTER
Designed for professional use. Thyratron trigger tube limits shutter contact current to 100 microamp. Converter charges storage capacitors to 90% of full charge in 8 sec. Peak current drain from nickel-cadmium battery during charging is only 5 amp, and idling current is 350 ma. 1,500-cps oscillator uses toroidal saturable-core transformer. 900-v full-wave voltage-doubling circuit has its center grounded, so maximum voltage above or below ground is 450 v.-H.
