Abstract：As a significant part of the future energy landscape, reliability of wind turbine is vital. Power electronic converters are widely used in high power wind turbines. The reliability of the wind power converters is becoming an issue deserved more attention, due to the complex environment and special operation of wind turbines. This paper presents a review of the aging-to-failure mechanisms of power electronic converters in the context of wind turbine application, as well as states the impacts of incessant thermal cycling associated with low frequency operation on the generator side and the random wind turbulence. Condition monitoring methods of wind power converters are analyzed for improving the reliability and availability of wind turbines. The development trends are also discussed.
