Abstract

This thesis describes multilevel converters (MLC) designed for use with a repurposed electronic vehicle battery (battery 2nd life). MLC is of particular interest due to the low harmonic distortion content and reduced voltage stress in the switching devices. A detailed study of the MLC topologies and modulation techniques is presented. Space vector modulation is analysed and implemented to evaluate the converter. A comprehensive assessment of the MLC is presented using wide bandgap (WBG) devices highlighting the devices’ thermal and high switching frequency features.
