Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

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.
