摘要：A high voltage power supply is formed by three discrete circuits (12, 14, 16)energized by a battery (18) to provide a plurality of concurrent output signals floating ata high output voltage on the order of several tens of kilovolts. Each circuit has a

regulator stage (20, 28, 36). In the firsttwo circuits, the regulator stages are pulse widthmodulated and include adjustable resistances (R1, R2) for varying the duty cycles of pulsetrains provided to corresponding oscillator stages while the third regulator stageincludes an adjustable resistance (R3) for varying the amplitude of a steady signalprovided to a third oscillator stage. In the first circuit, the oscillator (22), formed by aconstant current drive network and a tuned resonant network including a step-uptransformer (46), is coupled to a second step-up transformer (24) which, in turn, suppliesan amplified sinusoidal signal to a parallel pair of complementary poled rectifying,voltage multiplier stages (76, 76') to generate the high output voltage. Each of the othertwo circuits include oscillator drive stages (30, 38) which, together with isolationtransformers (32, 40) provide output signals floating at the high output voltage.
