一种低电容单相三开关共地AC-DC变换器的拓扑推导与谐波抑制

Buck–boost output, low leakage current, and electrolytic capacitor-less are three important requirements for single-phase nonisolated ac–dc converters. Existing topologies can only meet some of these requirements and involve a large number of components. Through topology derivation, this article proposes a single-phase common-ground ac–dc converter that meets all three requirements simultaneously,...
