一种具有对称Y-Δ连接变压器的高频单级容错三相双向AC/DC变换器

This article presents a single-stage isolated three-phase bidirectional ac/dc converter with symmetric Y-Δ connected transformers, which implements ac/dc buck conversion, high-frequency electrical isolation, and high power factor for ac side (PF > 0.99). The converter can be utilized between the ac bus and the dc bus in ac-dc hybrid microgrid and in other applications where three-phase bidirection...
