Abstract: An asymmetrical power converter and a method of operation thereof. According to a first aspect of the present invention, the asymmetrical converter includes (1) first and second transformers having serially-coupled primary windings and differing turns ratios; (2) a first power switch coupled to a first end of the serially-coupled primary windings; (3) a second power switch coupled to a node between the serially-coupled primary windings and (4) a capacitive element coupled to a second end of the serially-coupled primary windings to maintain a volts-second balance thereacross during alternate switching cycles of the first and second power switches.

Abstract: An integrated power converter and a method of operation thereof. The integrated power converter, having an energy storage device, includes: (1) a conditioning circuit coupled to the energy storage device and having a control switch for affecting a voltage across the energy storage device, (2) an asymmetrical half-bridge power circuit coupled to the energy storage device and having first and second power switches capable of being alternately activated to conduct current from the energy storage device to an output thereof and (3) a controller for controlling activation of both the control switch and the first and second power switches as a function of a characteristic of the output thereby to enhance a regulation of the output.
