Abstract

This paper discusses the control mechanism and simulation of a three-phase IM powered by a four-level diode clamped multilevel inverter. In the fields of power trade, reactive power compensation and interfacing with clean energy sources, they were chosen as the best alternative. The key aim of this study is to use a 4-level diode clamped multilevel inverter to control the torque and speed of an asynchronous motor (Induction motor). A multicarrier PWM control scheme for diode clamped multilevel inverter is proposed to achieve high quality sinusoidal output voltage with reduced harmonics. The designed system reduces switching losses when compared with other conventional methods. The suggested system is a viable alternative to the traditional approach for lowering switching losses and improving drive efficiency. The proposed circuit effectively controls motor speed while also enhancing drive performance by lowering total harmonic distortion, according to simulation results. This also shows that the suggested model easily controls the speed and torque of the machine. As a consequence, simulation is used to assess the system's efficacy.
