一种基于实时计算模式切换的单级双有源桥AC-DC变换器

In this article, a double degree-of-freedom variable control strategy with fixed frequency is proposed for a single-phase single-stage ac–dc rectifier based on dual active bridges. The proposed modulation strategy can achieve power factor correction without inner current ac current loop. In addition, the two control variables are calculated in real time without using look-up tables, and their comb...
