3-Phase 7-Level Diode Clamped Inverter for Standalone Application

Abstract

This article presents a three-phase, seven-level diode clamped multilevel inverter method. This circuit can be used for applications requiring medium to low industrial power. The three operational modes for this three-phase, seven-level, diode-clamped MLI structure are presented in this study. It consists of three phases each phase consists of the upper and lower leg each leg consists of 12 switches. This circuit operation is presented and simulated with PWM control techniques and output waveforms are obtained. By using this circuit design the THD is better.
