This document summarizes a research paper that proposes and analyzes a multilevel line-commutated inverter topology for solar PV-based grid-connected inverters. The proposed topology uses a multi-winding transformer to provide multiple voltage levels and reduce harmonic distortion in the line current compared to a conventional square-wave inverter. A three-level implementation is modeled in Simulink and experimentally tested. Simulation and experimental results show the proposed topology reduces total harmonic distortion and improves power transfer characteristics compared to a conventional line-commutated inverter.
