ABSTRACT:
A regulated power supply for high voltage pulsed loads. An AC main or inverter circuit feeds the primary of a transformer which has a tapped secondary. The full secondary voltage is rectified through a diode to charge a main capacitor through a ground-end, low-voltage solid state control circuit. A sensing circuit detects the desired level of main capacitor charge and controls the solid state conductive element into current cutoff, by injecting a voltage step which holds off further main capacitor charging until the next load current pulse. The solid state circuits control operate at low level (ground-end of the high voltage main capacitor) and residual power supply energy is automatically shunted to an unregulated tapped output.
