Implementation of multilevel inverter for controlling induction motor

Abstract

Multilevel inverters hold appealing highlights and its utilized as a part of extensive variety of applications. The utilization of more switches in the ordinary design represents a confinement to its wide range application. In this paper new multilevel converter has been proposed. The seven level inverter output has been accomplished by altering customary topology of five level inverter and inverter configuration primarily engaged to diminish the aggregate harmonic distortion of the output to improve the performance of the framework. switching loss highly decreased by diminishing the quantity of the switches utilized. the number of levels has been increased. Along these lines, a restored 7-level multilevel inverter topology is presented incorporating minimal number of unidirectional switches, gate trigger circuitry, decreasing size and establishment cost. Energy created at the time of braking is additionally used efficiently by regenerative braking.
