基于瞬时功率平衡的单级双向AC-DC DAB变换器自然功率因数校正调制方法

In this article, an instantaneous power-balance-based modulation method with natural power factor correction is proposed for a single-stage bidirectional ac–dc dual active bridge (DAB) converter. The condition for realizing natural power factor at the ac port is derived, and three single-variable modulation methods (namely, phase shift, secondary duty-cycle, and primary duty-cycle) are proposed an...
