电动汽车充电器全桥三电平LLC谐振变换器的调制方法

This paper proposes a modulation method for a full-bridge three-level LLC resonant converter. The target converter is known to enable fixed frequency operation, small resonant inductance ratio, and zero-current switching operation of rectifier diodes under wide output-voltage variation. Therefore, it is suitable for an application such as in battery chargers. A new parameter named “master duty,” w...
