A Novel Single-Source Eleven-level Quintuple-Boost Inverter with reduced Component Count

Abstract

A single source eleven-level inverter with reduced component count with quintuple voltage boosting ability is presented in this paper. It comprises of thirteen power switches, one power diode, and three capacitors. The voltage stress across the switches is reduced as it does not require an H-bridge circuit to generate negative voltage levels. A simple nearest level control (NLC) which is a fundamental switching frequency-based technique is used to provide gate pulse to the inverter circuit. Comparison with recent topologies in terms of switches, diodes, sources, capacitors used in numbers, and the voltage boosting ability is done to show the merits of the presented topology. The total harmonic distortion (THD) is 8.6% which is near to acceptable limits as per IEEE 519-2014 standard. Finally, experimental and real-time results are presented to validate the operability of the proposed SCMLI topology for different loading conditions.
