Abstract

This paper presents a quasi-Z-Source inverter based induction motor drive system. The speed of the induction motor is controlled by using V/f control method. Also the proposed system has an ability to compensate the voltage sags and swells. The advantage of the proposed system is that no energy storage component is required to compensate the voltage sag/swell. The operating principal of the proposed quasi-Z-source inverter based system is described and Matlab/Simuliink simulation is presented to verify the proposed concept and theoretical analysis.
