Abstract

In this paper a detailed quantitative comparison between two competing high-voltage converter technologies is performed, namely series connection of semiconductor power devices versus multilevel converters. The comparison is based on converter losses (conduction and switching), total harmonic distortion, and distortion factor for the output phase and line voltages at different modulation frequency ratios. A new method is presented for calculating the conduction loss of cascaded-type multilevel converters which use carrier-based pulse width modulation.
