ABSTRACT:
A voltage converter circuit for providing electrical energy to a capacitive load, the converter circuit having a pulse transformer having primary and secondary circuits. Pulse signals are provided in the primary circuit by thyristor devices. The thyristors are quenched by circuitry contained in the secondary circuit, comprising a storage capacitor which conducts a quenching current through a bank of power transistors to at least a portion of a secondary winding. A magnetizing current from a further secondary winding in the secondary circuit is utilized to charge the capacitor.
