Comparison of Z-Source Inverter Fed Induction Motor with Traditional Source Inverter Systems
並列摘要
This study presents an impedance-source inverter fed (or Z-source converter) induction motor and its control characteristics compared with other traditional inverters. The impedance source inverter employs a unique impedance network coupled with inverter and rectifier; it overcomes the conceptual barriers and limitations of the traditional voltage-source converter (abbreviated as V-source converter) and current-source converter (abbreviated as I-source converter). By controlling the shoot-through duty cycle, the z-source inverter system provide ride-through capability during voltage sags, reduces line harmonics, improves power factor and extends output voltage range. Analysis and simulation results are presented to demonstrate these features.
