As a kind of efficient and clean renewable energy, wind energy receives much concern. Wind energy conversion system （WECS） based on permanent magnet synchronous generator （PMSG） has become one of the most significant development directions of wind energy technologies because of its outstanding comprehensive superiority. This paper discusses the structures, driven types and operation characteristics of PMSGs in WECSs. Then the topologies, controls and applications of the power converters suitable for WECSs based on PMSG are illustrated. The development trend of WECS based on PMSG technologies are analyzed finally. With rapid development of wind energy and its related technologies, the WESCs based on PMSGs will have broad prospects.
