Single-Phase Multilevel Inverter with a Coupled Inductor

Project Code :TEMAPE400

Objective

The main objective of this project is to develop a novel single-phase seventeen-level inverter topology that reduces the component count and overall cost, while ensuring high-quality output voltage and minimizing current stress on the switches.

Abstract

This paper proposes a novel single-phase seventeen-level inverter topology that utilizes three DC sources and a coupled inductor, aiming to reduce size, component count, and overall cost. The integration of coupled inductors enhances the inverter’s capability to produce high-quality output voltage while minimizing current stress on power devices. A topology-specific level-shifted pulse-width modulation (LS-PWM) technique is introduced and discussed in detail. The proposed design offers a compact, efficient, and cost-effective solution for multilevel inverter applications, particularly in medium- and high-voltage scenarios.

Keywords: Coupled inductor, multilevel inverter (MLI), switch count.
