Simulation of Impedance Source Inverter Driven Single Phase Induction Motor

This work presents an alternative power conversion topology that can buck or boost the input voltage or current with linear and non-linear load depending upon duty ratio and modulation index in single stage conversion with the help of Impedance source passive Network (L&C), which is usually known as Z-Source. The objective of this paper is to demonstrate a low-cost, efficient, and reliable inverter for various load. The simulation and the performance of single-phase induction motor is studied with the control of single phase Z-source inverter. The unique features of Z-source network is it acts as filter which reduces the line harmonics and shoot-through duty cycle, extends the output ac voltage range of inverter, improves power factor and increases reliability.
