Z-Source Inverter Control of Induction Motor Control

Abstract

In induction motor control CSI and VSI techniques were used earlier which produces undesirable harmonics. This harmonic results in reduction in efficiency of induction motor speed control. In order to overcome this drawbacks Z-Source inverter is been used. By using this inverter the harmonics are reduced which helps in giving better variable speed for speed control of induction motor. In this Z-source inverter consists of two inductors and two capacitors which acts as filter that reduces harmonics.
