I. Introduction
The renewable energy resources are of paramount importance while setting up the power generation policies. Among all the non-conventional energy resources, wind power is recognized as one of the valuable resource [1]. Compared with steam/hydro/gas turbines used in traditional power plants, wind turbines (WTs) are usually operated in the harsher environment and therefore, have relatively higher failure rates [2]. A typical wind energy power conversion system (WECS) is composed of wind turbine structure, generator and power conditioning system (i.e power converters namely- AC-DC rectifier, buck/boost converter, and inverter-) as shown in Figure 1.
