Power losses Analysis in Frequency Domain of IPMSM Drive fed by Cascaded H-Bridges Multilevel Inverter

Abstract

Power losses analysis of an IPMSM drive is a challenging task, especially, when multilevel inverters are employed. This study focuses on an IPMSM drive fed by a Cascaded H-Bridges Multilevel Inverter (CHBMI) controlled by MC-PWM strategies, employing a frequency domain power analysis approach based on Discrete Fourier Transform (DFT).
