Abstract
Si fast recovery diodes currently limit the performance of many IGBT powered systems. In this paper SiC Schottky diodes are proposed as an alternative technology. The static and dynamic performance of the SiC Schottky diodes is evaluated and comparison made with Si PiN diodes at currents of up to 20 A and DC link voltages of up to 400 V. The results demonstrate the effectiveness of the SiC devices in reducing the overall system losses and the levels of EMI generated by switching transitions
