Design and Simulation of a Variable 15-Level Asymmetrical CHB Multilevel Inverter using SHE-PWM Technique
Supervisor: Dr. Md. Ahsanul Alam, Associate Professor & Controller of Examinations · Green University of Bangladesh
Research Focus
Analyzing total harmonic distortion (THD) reduction across Cascaded H-Bridge Multilevel Inverters (CHB-MLI) with asymmetrical DC source ratios.
Methodology
Implementing Selective Harmonic Elimination Pulse Width Modulation (SHE-PWM) switching angles to suppress lower-order harmonics (3rd, 5th, 7th, 11th) and improve output waveform quality and conversion efficiency.
