Abstract

This Project deals with an Embedded Z-source inverter to control the three phase induction motor. The Z-source inverters are recent topological options for buck?boost energy conversion with a number of possible voltage and current-type circuitries. The common advantage of Z-source inverter and Embedded Z-source inverter is the inclusion of an LC impedance network, placed between the dc input source and inverter bridge. The drawbacks of the conventional Z-source inverters are more harmonic, less reliable, more diode blocking voltage and capacitor size also high. By introducing Embedded Z-source inverters, the drawbacks of the conventional Z-source inverter can be eliminated and also gain produced is same as that of Z-source inverter. It can produce smoother and smaller current or voltage maintained across the dc input source without using any additional passive filter, less cost and low harmonic distortion. The project is further carried to control the induction motor drive which is used in paper mills, textile mills and cement industries etc.
