Vijaya Raju Vasipalli, Prof. S. P. Phulambrikar

Abstract: This paper proposes the Doubly Fed Induction Generator (DFIG) System with Matrix Converter and DFIG system with Back to Back Converter. Matrix Converter is very efficient one in DFIG system than Back to Back Converter in Design constraints, Power quality, losses, and controlling. Both converters are controlled by Indirect Space Vector Modulation (ISVM) technique. LCL filters are designed for both converters. All results are simulated on MATLAB/SIMULINK software. Performance of the system is analysed by FFT window.
