Abstract
A switched-capacitor-based multilevel inverter (MLI) topology is given in this study. The suggested MLI employs fewer power switches and has an extendable configuration that allows it to increase the number of output voltage levels while using a single DC source. To produce gate pulses, the nearest level control method is used. The proposed topology’s priority has been determined by comparing the proposed structure to other similar topologies. The suggested seven-level and extended 13-level MLIs are developed into a laboratory-scale prototype and evaluated under load variation and variation in the modulation index conditions. All the results demonstrate that the inverter topology operates effectively in various real-time environments.
