Abstract :

Wind Turbines using Synchronous generator towards generate power and transferred to reliable grid system. This paper proposed with and without Quasi Z–Source inverter in PMSG based wind turbine. The closed loop control of shoot through duty cycle is designed to get desired dc bus voltage. Voltage Fluctuations and high harmonics generated in without Quasi Z–Source inverter. Integration of generator side three switch buck type rectifier and grid side Quasi Z–Source inverter is employed towards buck and boost capabilities as well as suppress the harmonics of wind system. Maximum Power Point Tracker (MPPT) is implemented by adjusting shoot through duty cycles of the Quasi Z–Source network. The proposed system has verified by using MATLAB/SIMULINK Environment.
