Abstract: As a source of green and abundant energy wind power is proposed as one of the main new power sources and is day by day gaining more and more importance. In last few decades, different types of wind turbines are developed to increase the maximum power capture with minimum cost and expansion for use of wind turbine for onshore and offshore applications. This paper focuses on the Power Converter Topologies used for renewable energy resources for wind farm application. In wind energy conversion system four main types of generators used are Squirrel Cage Induction Generator (SCIG), Doubly Fed Induction Generator (DFIG), Wound Field Synchronous Generator (WFSG) and Permanent Magnet Synchronous Generator (PMSG).PMSG is directly coupled to wind turbine and hence is called as Direct Driven Generator. This paper mainly discusses Power Converter Topologies in use with Permanent Magnet Synchronous Generator.
