Performance characteristics of five level diode clamped multilevel inverter for induction motor drives

Abstract

The object of this paper is to proposes a method for induction motors with adjustable-speed drive consisting of two five level diode-clamped converter connected back-to-back with transformer less configuration in medium voltage application. This paper delivers a remedy for the voltage stabilizing problem which occurs during the implementation of split dc capacitors. This problem has been reduced by using suitable switching technique in the proposed configuration. Multi carrier pulse width modulation technique has been dropped back behind the advanced Space vector PWM technique. The voltage and current harmonic values of the induction motor output were reduced by using the space vector PWM switching technique.
