Abstract

This paper presents the temperature and switching rate dependence of 1.2 kV/30 A SiC Schottky diode energy losses in clamped inductive switching circuits with 1.2 kV/30 A SiC MOSFETs as the switching transistors. The devices are tested under an ambient temperature range that spans from -75°C to 175°C and with switching rates that span from 10 to 100 A/μs. Due to the abruptness of the diode turn-OFF, low series resistance and the lack of reverse recovery, SiC SBDs are known to exhibit ringing or electromagnetic oscillations in the presence of parasitic inductances and high switching rates [1]. The impact of these electromagnetic oscillations on the switching energy, the dependence of the switching energy on temperature and the switching rate (di_DS/dt) is the purpose of this paper's investigation.
