Abstract
The invention relates to a power supply circuit utilizing a DC input tied to the primary windings of two transformers. A pulse source drives either primary through a selector switch which selects the desired primary to produce a pulsed transformer output of desired polarity. The transformer secondary windings produce a voltage output discharged by a load supplying capacitor. The voltage output is maintained at a desired polarity and at a peak level by periodically pulsing the load supplying capacitor with the same amount of energy taken by the load.
