一种具有次级主动连接的混合移相控制三电平与LLC DC-DC变换器

This paper proposes a hybrid phase-shift-controlled three-level (TL) and LLC dc–dc converter. The TL dc–dc converter and LLC dc–dc converter have their own transformers. Compared with conventional half-bridge TL dc–dc converters, the proposed one has no additional switch at the primary side of the transformer, where the TL converter shares the lagging switches with the LLC converter. At the second...
