Abstract
The terminal ends of a center tapped primary transformer winding are connected to the positive polarity direct current input terminal through the anode-cathode electrodes of respective power silicone controlled rectifiers which are alternately triggered conductive and the center tap is connected to the negative polarity direct current input terminal. Simultaneously with each power silicon controlled rectifier, a corresponding commutating capacitor charge circuit silicon controlled rectifier is triggered conductive to establish a charge circuit for the corresponding commutating capacitor across the direct current input terminals. Each power silicon controlled rectifier is commutated not conductive by the charge upon the corresponding commutating capacitor applied in an inverse polarity relationship across the anode-cathode electrodes thereof through a commutating silicon controlled rectifier. The transformer secondary winding output is rectified and filtered to supply a direct current potential to a connected load.
