Comparison of soft and hard-switching effiency in a three-level single phase 60kW dc-ac converter

Research output: Contribution to book/anthology/report/conference proceedingArticle in proceedingResearch

Abstract

Efficiency measurements on a three-level single-phase soft-switched converter are presented and show a slightly improved efficiency compared with the hard-switched converter for output powers higher than 25 % of rated power. The resonant converter switches are Zero Voltage Switched (ZVS) and a simple resonant circuit is used. Increased resonant converter efficiency enables a reduction in the semiconductor size pr. watt output power or an increase the switching frequency.
