具有宽ZVS范围及低电压电流应力的LLCC谐振变换器

To address the problems of narrow soft-switching range and high voltage/current stress on resonant components in LCC resonant converters operating in phase-shift control mode, this article proposes a LLCC resonant converter with wide soft-switching range and low voltage/current stress. The converter adds a parallel auxiliary inductor at the input of LCC resonant tank, which widens the zero voltage...
