一种具有阶跃变频运行且减少有源和无源元件的隔离型双极性Buck-Boost AC-AC变换器

This article introduces a novel buck-boost ac–ac converter with identical bipolar operation and high-frequency voltage isolation. The proposed converter offers several distinguishing features compared to existing isolated converters: First, it provides a significant reduction in the number of active and passive components. Second, it supplies continuous input and output currents with low harmonic ...
