具有无功功率控制能力的单级多端口AC-DC-DC变换器

This article introduces a single-stage three-port ac–dc–dc converter designed to overcome the limitations observed in conventional two-stage converters used in grid-tied applications with multiple dc sources, such as hybrid energy storage systems and microgrids. Traditional two-stage converters, typically comprising a dc–dc converter followed by a dc–ac inverter, are hindered by the multiple power...
