Abstract: Conventional power system diverges from a Wind Energy Conversion System (WECS). The power output from a wind turbine system varies as the wind varies. Thus, management, design and analysis of WECS become difficult. Various approaches are available theoretically to cram the behavior of WECS. This paper, uses MATLAB simulink model of DFIG based WECS to study steady state characteristics. The analysis is performed to inspect the characteristics of wind and Doubly Fed Induction Generator model. For efficient generation of electricity, it is necessary to operate the wind turbine at variable speed. This is achieved by the Power Electronic Converters. Many designs of converters are available, depending on the aspects of economy, configuration and application. Now-a-days attention of the researchers is diverted towards the Doubly Fed Induction Generator (DFIG). The paper signifies the design, simulation and analysis of back-to-back converters for DFIG based Wind Energy Conversion System WECS. A 9- switch Back to Back converter is designed, simulated in the paper and the results are compared with traditional AC-DC-AC converter. The functioning of the converter is simulated by means of MATLAB/SIMULINK. Results of the simulation illustrate the improved DC link voltage, when compared to that of the conventional converter.
