Nearest level control for improving total harmonic distortion in a 13-level three-phase multilevel inverter
This research investigates the application of nearest level control (NLC) in a three-phase transistor-clamped H-bridge (TCHB) multilevel inverter (MLI) to enhance power quality and reduce harmonic distortion.

| Summary: | This research investigates the application of nearest level control (NLC) in a three-phase transistor-clamped H-bridge (TCHB) multilevel inverter (MLI) to enhance power quality and reduce harmonic distortion. The TCHB topology offers high performance with fewer components compared to traditional MLI configurations, making it particularly suitable for renewable energy applications. By operating at fundamental switching frequency, the NLC technique effectively minimizes switching losses while reducing total harmonic distortion (THD). The study includes MATLAB/Simulink-based simulation modeling and experimental validation using dSPACE, tested under varying load conditions. For a 13-level
