Abstract
Abstract:
On load, transformer primary tap changing is not
common in high frequency converters. This paper investigates a
new converter topology to drive primary tapped transformers.
The ideas that have been introduced previously are simply
implemented into existing converter topologies which have been
modified to accommodate a primary tapped transformer. The
effects of efficiency with variation of source voltage and duty
cycle are studied. It is shown that this topology can maintain a
load voltage for a much wider source voltage variation without
major sacrifices in efficiency.
