15-Level Inverter Topology of Reduced Switch Count With Power Loss Analysis

Abstract

A multi-level inverter surpasses the capabilities of a traditional inverter, have developed to accommodate voltage applications and finding widespread commercial use. While conventional inverters yield the output in the shape of a square, inverters with multilevel are employed to generate a waveform that closely approximates a sinusoidal one. In comparison to traditional inverters, the 15-level inverter exhibits advantages such as reduced THD, the power quality of output power is improved by using the DC link with higher voltages, and switching losses are reduced. Multilevel inverters achieve these benefits by utilizing a smaller number of switches and generate closer to sinusoidal output. This particular approach involves the use of ten switches to generate output of 15 levels, contributing to a simplified circuit design.
