一种用于高频隔离DC/DC变换器的对称磁通半匝变压器

A half-turn transformer with symmetrical magnetic flux is proposed for high-frequency-isolated dc/dc converters. The transformer structure can reduce the minimum number of turns from 1 to 0.5. By adopting a novel winding and circuit configuration, a symmetrical magnetic flux is realized to make full utilization of the ferrite core. A simple EI core, which is easily manufacture and commercially ava...
