一种用于电池充电的无控制串联谐振变换器，具有自动恒流转恒压特性及全过程高效率

Constant current (CC) and constant voltage (CV) outputs are required by electric vehicle chargers to comply with the battery profile, which are challenges to the wide operating range, accurate current and voltage control, and high efficiency of the battery chargers. This article proposes a control-free battery charger based on a series resonant converter that features an inherent automatic CC-to-C...
