Abstract

In this paper, four multilevel pulse-width-modulation methods are quantitatively characterized and compared: phase opposition disposition (POD), Space vector modulation with switching loss minimization (SVPWM-SLM), and selective harmonic elimination (SHE) of non-triplen harmonics up to the 15th and 27th harmonics, respectively. Inverter losses and efficiency, induction machine voltage, and current harmonics are analyzed. Analytical and simulation results using PLECS and MATLAB/Simulink for control systems are experimentally verified with a 1000-hp 4160-V neutral-point-clamped (NPC) adjustable-speed-drive (ASD) system.
