An assessment of H-bridge less grid-tied multilevel inverter with minimum device count and lesser total standing voltage

An innovative switched-capacitor-based inverter is proposed in this paper. The suggested converter can produce a five-level output voltage by utilizing minimal components (single dc source, six switches, and one capacitor). The proposed topology does not require an H-bridge setup at the load end to achieve the output voltage level. Furthermore, the proposed converter configuration and its operating principle are investigated in depth. A detailed power loss calculation of the suggested inverter and a comparison with another converter is presented. It demonstrates that the proposed inverter is more cost-effective and requires fewer components than competing inverters. The effectiveness of the proposed multilevel inverter is verified by using hardware in loop OPAL-RT OP4510 and further five-level inverter prototype has been verified by experimentally using dSpace 1103 controller.
