Abstract

In this paper, a Stand-Alone Induction Motor drive is controlled using an Impedance Source Inverter (ZSI). The Permanent Magnet Synchronous Generator (PMSG) is used as the variable speed wind turbine generator for the power generation. The Space Vector Pulse Width Modulation (SVPWM) controls the ZSI switches for generating constant voltage supply for driving the Induction Motor. In the proposed paper, the generator side diode rectifier and the load side ZSI is presented. The variable speed generator is modeled with the mathematical modeling of the PMSG machine equations. The performance of the PMSG obtained is efficient for a drive system. The PMSG designed for a power rating of 4kW. The ZSI eliminates the shoot-through problem and the SVM controlled switching reduces the harmonic contents for a drive application. The performance of the proposed design is verified in the results obtained. The results are generated using the MATLAB 7.
