用于功率流控制增强的异频调制三相交流-交流六边形斩波系统

This paper proposes a three-phase ac chopper system for the interconnection of various distributed generation (DG) farms or main utilities to enhance the active and reactive power flow control. The absence of large energy storage component in direct ac-ac converter makes the system footprint small and reliable. As the interface for different ac sources, the presented converter can be configured as...
