Design of multilevel inverter topology using less number of switches

Abstract

The advent of the multilevel inverters has been in increase considering the fact that the final decade. The primary choice of the multilevel inverters in the subject of high power medium voltage energy control. These new varieties of converters are suitable for high voltage and high power application due to their potential to synthesize waveforms with higher harmonic spectrum. The multilevel cascaded inverter was once presented in Static VAR compensation and power process. In this paper presents a new process for getting a multilevel output and in addition uses PWM control systems. In this procedure, the number of switches used for the dc to ac conversion is diminished so this dc to ac conversion enormously reduces the at first cost. This manner reveals some attractive points which fit in industrial applications.
