Abstract
A unified power architecture for generating high frequency switched power to a load is provided which includes a number of input branches, each input branch receiving direct current (DC) power from a power source. Each input branch includes a switch device coupled to a storage device for generating input pulses, a transformer including a primary winding set receiving the input pulses, and a reset section generating a reset current for setting a core of the transformer. An output section is provided which includes a plurality of windings around a secondary of each transformer of each of the input branches, the output section generating an output pulse including components of each of the input pulses.
