Abstract
A power converter circuit has an inductor input and switching means to put a pair of capacitors alternately in series or in parallel. By pulse width modulating between the states, the voltage on the capacitors can be controlled over a two to one variation of the input voltage. A pair of transformer isolated power converter sub-circuits can be connected to the capacitors, and their outputs can be combined to provide a single controlled output voltage.
