A review of power converter topology used with PMSG based wind power generation

Wind energy conversion systems are becoming popular in the research areas of renewable energy resources. The commonly used generators with wind energy conversion system (WECS) are Squirrel Cage Induction Generator (SCIG), Doubly Fed Induction Generator (DFIG), Wound Field Synchronous Generator (WFSG) and Permanent Magnet Synchronous Generator (PMSG). Recently PMSG is gaining popularity as it has many advantages over conventional generators. Due to the variable nature of wind, PMSG cannot be directly coupled with the grid. An intermediate power electronic link needs to be provided between the generator and the grid. Many power electronic converter topologies are being used with PMSG. In this paper a review of recent and past grid connected converter topologies, used with PMSG for wind power generation, has been presented.
