A NEW PER-PHASE CONTROL SCHEME FOR THREE-PHASE FOUR-LEG GRID-CONNECTED INVERTERS

摘要

Voltage source inverters (VSIs) are key components of microgrids, because they provide advantages such as power quality, reliability and flexible control for power systems. In recent years, there has been increased interest in three-phase four-leg VSIs due to the benefits they offer to the three-phase four-wire distribution systems and microgrids.
