Mohammad Abdul Hakeem | Hazeera Sulthana

Abstract: This paper presents an Impedance Source Inverter for A. C electrical drives. The impedance source inverter employs a unique combination of inductor and capacitor impedance network couple with inverter main circuit and rectifier. By controlling the short circuit provide through duty cycle, voltage, current and the impedance source inverter systems using IGBT provide ride-through capability during voltage sags, reduces line harmonics, buck-boost the voltage, high reliability, and extends output voltage range. Analysis, simulation, and experimental results will be presented to demonstrate these new features. It reduces pre-dominate harmonics, electromagnetic interference noise and it has low common made noise. MATLAB simulations have been performed to analyses these issues.

Keywords: pre-dominant harmonics, motor drives, Z-source inverter
