一种用于光储电网侧集成的单级高频链中压交流转直流变换器

This article presents an innovative galvanically isolated medium-voltage ac (MVAC) to low-voltage dc (LVDC) converter for MV grid integration of utility-scale renewables and storage. The converter supports bidirectional power flow at any power factor with high power quality. In the proposed solution, transformers are operated at high frequency, significantly reducing size and weight compared with ...
