Abstract
Abstract:
Tapped transformers are often used for voltage regulation in low frequency applications. Tapped
secondary transformers are found in high frequency converters but usually only on the secondary windings to
provide multiple isolated output voltages. This paper is aimed at investigating the use of multiple switched
primary transformer taps in applications where the supply voltage varies over a wide range. A few of the standard
converter topologies, modified to accommodate multiple primary taps, are shown and the principle is
demonstrated on a push-pull topology.
