Abstract: An FET full bridge regulator has a driving transformer for the gates of the power FETs of the regulator, and a driving circuit for the primary of the driving transformer, the driving circuit including a full bridge formed by first and second sets of driving FETs, each set formed by a complementary pair of FETs and being connected across the transformer, primary, one FET of each set being driven ON to together form a series of conducting paths across the primary of the transformer in the absense of driving signals.The voltage supply for the driving FETS in the driving circuits of the primary of the driving transformer includes a resistance across which there is developed a voltage proportional to the current drawn by the driving transformer primary in each half cycle of its operation for reducing imbalance between the half cycles.

Abstract: A switching regulator designed for high power high current transfer is adapted for reducing leakage inductance and heat dissipation. The switching regulator comprises a transformer/receiver assembly utilizing a planar winding configuration in the transformer. The planar secondary winding is a short, large area thermo-path interface for heat dissipation in a cooling medium.

Abstract: The disclosed supply utilizes the capability of two-way power flow, from a DC source to the load and from the load to a DC source, so as to be able to track a desired output wave form while running reactive loads. This method of operation requires minimum filtering for loads of various power factors and transient characteristics. Two equal and opposite DC sources, such as batteries, furnish and accept current, through switches, to and from an inductor-capacitor filter to which the load is connected. A feed-back circuit compares the voltage furnished to the load with a reference of the desired output wave shape, so as to control the switches in such manner as to force the output voltage to follow that wave form.
