一种用于车载充电器的高效单开关开关电容部分功率变换器

This article proposes a novel single-switch switched-capacitor (SC) series-connected partial power converter (S-PPC) for the dc–dc stage of an unidirectional on-board charger. The proposed step-down S-PPC features two key aspects: i) it performs partial power processing, reducing the active power processed by the dc–dc stage, and ii) it is transformerless, with the SC cell providing the necessary ...
