Abstract

An improved series inductor/parallel inverter power stage and power staging method for a transistor controlled DC-DC power converter in which the integrating capacitance is located in the output of the power stage transformer and the series inductor has a secondary winding connected across this capacitance for transferring stored energy from the inductor primary directly to the transformer output rather than through the transformer, and current flow through the transformer primary is controlled by two parallel, alternately conducting pulse-width-modulated transistors in a manner such that only a single transistor is located in the main current flow path at any given time. The improved power stage is characterized by reduced power dissipation and peak voltage stresses on the transistors, increased simplicity, and improved reliability.

A DC-DC power converter having at least two improved power stages of the invention arranged in parallel and adjusted for conduction of preset fractions of the total power in phased relation.
