Abstract

This paper analyses a six-phase induction drive (SPID) powered by a five-level Packed U Cells (PUC) multilevel inverter (MLI) for high-power applications. The MLI produces a symmetrical 5-level output voltage waveform through sensor less self-capacitor voltage balancing control. This ensures that the voltage across the capacitor stays at half the value of the DC source. This control method reduces system complexity and enhances performance. The proposed system requires fewer components than conventional cascade h-bridge (CHB) fed drives. The proposed system is similar to drives using Flying Capacitor (FC) and CHB MLI technology. The system is designed to power a SPID with a distributed neutral load, and its functionality is simulated using MATLAB/Simulink software. Finally, a prototype experimental setup has been developed in the laboratory to validate the analytical development of the proposed system.
