SiC Traction Power Converter for Electromobility

Abstract

The paper describes the design of a converter for use in automotive industry and it is designed as a so-called “Full SiC” converter. It aims to develop a traction converter with a high-power density of 100 kW/l, which brings the parameters close to the goals of the U.S. DRIVE project. The developed SiC converter should achieve a power of at least 200 kW using minimum switching frequency of 20 kHz with 900 VDC in the dc-link powered from the traction battery while reaching efficiency above 99%.
