基于变占空比调制的三相双有源桥变换器时域分析与优化

The duty-cycle control (DCC) modulation scheme for the three-phase dual-active-bridge (3p-DAB) dc–dc converter is a promising three degree-of-freedom modulation scheme which can extend the converter's soft-switching range and reduce conduction losses under partial loading and wide voltage variations. However, the prior suggested methods to implement DCC in 3p-DABs have drawbacks, such as requiring...
