HIGH VOLTAGE POWER SUPPLY Abstract 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 at a high output voltage on the order of several tens of kilovolts. Each circuit has a regulator stage (20, 28, 36). In the first two circuits, the regulator stages are pulse width modulated and include adjustable resistances (R1, R2) for varying the duty cycles of pulse trains provided to corresponding oscillator stages while the third regulator stage includes an adjustable resistance (R3) for varying the amplitude of a steady signal provided to a third oscillator stage. In the first circuit, the oscillator (22), formed by a constant current drive network and a tuned resonant network including a step-up transformer (46), is coupled to a second step-up transformer (24) which, in turn, supplies an 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 other two circuits include oscillator drive stages (30, 38) which, together with isolation transformers (32, 40) provide output signals floating at the high output voltage.
