Abstract:
Described is a hybrid electronic and magnetic structure that enables a transformer with fractional and reconfigurable effective turns ratios (e.g. 12:0.5, 12:⅔, 12:1, and 12:2) and hereinafter referred to as a Variable-Inverter-Rectifier-Transformer (VIRT). A VIRT is valuable in converters having wide operating voltage ranges and high step-up/down, as it offers a means to reduce turns count and copper loss within a transformer while facilitating voltage doubling and quadrupling. Such characteristics are beneficial for reducing the size of a transformer stage in many power electronics applications, such as USB wall chargers. In embodiments, a VIRT comprises a plurality of switching cells distributed around a magnetic core and coupled to half-turns wound through that core. By controlling operating modes of the switching cells, it is possible to gain control over flux paths and current paths in the transformer.

Claim (Index 30):
A variable-inverter-rectifier-transformer, comprising:\n a transformer having a turns ratio, wherein the transformer comprises a magnetic core; a first rectifier coupled to a secondary side of the magnetic core, wherein the first rectifier comprises a first half-bridge cell and a second half-bridge cell; a second rectifier coupled to the secondary side of the magnetic core, wherein the second rectifier comprises a first half-bridge cell and a second half-bridge cell; a third rectifier coupled to the secondary side of the magnetic core, wherein the third rectifier comprises a first half-bridge cell and a second half-bridge cell; and a fourth rectifier coupled to the secondary side of the magnetic core, wherein the fourth rectifier comprises a first half-bridge cell and a second half-bridge cell; wherein the first rectifier operates at a first rectifier operating mode; wherein the second rectifier operates at a second rectifier operating mode; wherein the third rectifier operates at a third rectifier operating mode; wherein the fourth rectifier operates at a fourth rectifier operating mode; and wherein the turns ratio is based upon the first rectifier operating mode, the second rectifier operating mode, the third rectifier operating mode, and the fourth rectifier operating mode.
