Design and Analysis of Multilevel Inverter Topology using less number of Switches

Abstract

The emergence of the multilevel inverters has been in increase since the last decade. The main choice of the multilevel inverters in the area of high power medium voltage energy control. These new types of converters are suitable for high voltage and high power application due to their ability to synthesize waveforms with better harmonic spectrum. The multilevel cascaded inverter was introduced in Static VAR compensation and drive system. In this paper presents a new technique for getting a multilevel output and also uses PWM control techniques. In this technique, the number of switches used for the dc to ac conversion is reduced so this dc to ac conversion significantly reduces the initially cost. This technique exhibits some attractive features which suits in industrial applications.
