Comparison of power quality index between the Back to Back and Matrix Converters for Wind Energy

This study analyzes the performance between back to back and the matrix converters used in wind power system based on doubly fed induction generator (DFIG). The aim of this comparison is to determine which converter is well exploiting wind power generation. It is defined as a comparison for each topology in controls, losses, and the current quality generated by the DFIG, every part is given in details with its simulation result. Comparison of power quality index between the two Converters indicates that the better performance are obtained when DFIG is fed by the matrix converter. Verification of the analytical results is done using MATLAB simulation software.
