Abstract

In this paper a comparison between two different types of semiconductors for the use in an on-board power supply is being made with regard to losses, switching characteristics and DC-link design. Standard silicon IGBT´s are compared to SiC MOSFET´s in the same housing on the basis of equal voltage overshoots under hard switching conditions. The characteristics of both devices result in different limitations for the converter design.
