Abstract:
This work evaluates a Si-SiC hybrid switch consisting of a silicon IGBT and a silicon carbide MOSFET in parallel as well as an optional diode. The focus is to evaluate the utilization or not of a discrete diode in the hybrid switch. This work considers the use of two diode technologies: silicon fast recovery diode, and silicon carbide schottky barrier diode. Switching energy of the Hybrid Switch with each diode technology is evaluated using double pulse test. Losses in a 540 V/ 30 kVA inverter using the Hybrid Switch are calculated to evaluate and compare the technologies.
