In response to rising expectations for more efficient and better power generation, the switched-capacitor multilevel inverter (SCMLI) was developed. Most recently, SCMLIs were created to allow for step-up ac output via inversion and single-stage voltage boosting. This study presents a boost type single source nine-level (9-level) SCMLI that uses two capacitors and one diode in an effort to reduce the number of components. The capacitor's voltage boost from a single source is achieved through the series-parallel connecting procedure. No more than twice the input voltage can be applied to the semiconductor devices under any given condition. In order to raise the voltage levels without adding more dc input, the suggested SCMLI can be expanded with a minimal number of components. After a thorough evaluation of the power losses and circuit performance, the design is confirmed to be superior by comparing it to newly designed single-phase 9-level MLIs. In order to confirm the key characteristics of the 9-level SCMLI in dynamic operational settings, we offer comprehensive simulation and experimental findings.
