Design and Implementation of Improved Z-Source Inverter Fed Induction Motor for Wind Applications

This paper presents the simulation and implementation of Z-source inverter fed induction motor using PWM technique.The Z-source inverter employs a unique impedance network couple with inverter main circuit. Z-source inverter is used to reduce the line current harmonic, improves the input power factor, high reliability and extends output voltage range. Pulse Width Modulation variable speed drives are increasingly applied in many new industrial applications that require superior performance. PWM technique is used to control the frequency and voltage. It is also used to reduce the line current harmonics. The circuit will be simulated using MATLAB and implemented using embedded controller. Both simulation and hardware results will be verified.
