A New Single-Source Switched-Capacitor Based Seven-Level Boost Inverter Topology with Reduced Part Count and Voltage Stress

The use of multi-level inverters is a widespread and effective solution for solar power plants, wind farms, and other types of renewable energy sources. A novel switched-capacitor multi gain inverter topology (SCMGIT) is proposed in this paper. The research presents a SCMGIT that, with a single dc source, can produce seven distinct voltage levels at a voltage-boosting of three times the original input. The proposed SCMGIT exhibits several noteworthy characteristics, including self-balancing capacitor voltages, fewer switches with decreased voltage stress, and bipolar voltage generation without the usage of a backend H-bridge. A thorough comparison with other SC inverter has been performed in the article to highlight the benefits of the suggested SCMGIT. An analysis of the proposed SCMGIT has been investigated, and verified by simulation and experimental testing with a low prototype.
