ABSTRACT:
A power supply for repetitive discharge apparatus such as a laser comprises an unregulated DC source, a primary storage capacitor, a discharge capacitor forming part of the apparatus and an energy feedback circuit between the discharge and storage capacitors operative to return to the storage capacitor energy greater than that required for a predetermined charge level on the discharge capacitor. A switch responsive to the voltage on the discharge capacitor operates a divert excess charging current into resonant charging elements in the feedback circuit for return to the primary storage capacitor. Transfer of the excess charging energy is accomplished nondissipatively to provide highly efficient cycle by cycle voltage regulation.
