Modeling and Simulaton of Three Stage Interleaved Boost Converter Based Wind Energy Conversion System

This paper deals with modeling and simulation of three stage interleaved boost converter (ILBC) based induction motor drive fed from wind generator. The output of wind generator is converted into DC using a three phase uncontrolled rectifier. This voltage is boosted by using ILBC with reduced current ripple with three stages ILBC is proposed for this purpose. The output of the ILBC is converted into three phase balanced ac using a three phase inverter, which feeds a three phase induction motor. The simulation results for single pulse width modulation (PWM), sine PWM and space vector modulation (SVM) are presented.
