一种基于单极性移相调制策略的新型双向高频隔离直接AC/AC变换器

This article introduces a novel bidirectional high-frequency isolated direct ac/ac converter with unipolar phase-shifted modulation strategy based on double dc modulation indexes. The main idea of topological construction is that the non-isolated two-level nondifferential bipolar direct ac/ac converter is combined to the bidirectional phase-shifted full-bridge converter, which inherits the advanta...
