The SiC Power Revolution is Ready for High-Volume Car Manufacturing

Manuel Gärtner

STMicroelectronics

Abstract
Early adopters are already receiving significant quantities of SiC devices as we ramp up for the broader automotive industry. SiC wide-bandgap characteristics enable extraordinary efficiency in EV traction systems, on-board chargers, and DC-DC converters, as well as new applications including climate compressors, fuel cell power DC-DC, and high-speed air compressor pumps.By 2025, most European carmakers will have transitioned to the 800V DC bus domain where the high-voltage efficiency and thermal performance of SiC is even more appealing.The SiC revolution has many strategic implications and we will describe ST's manufacturing and vertical integration initiatives to meet the mounting demand, the ambitious electrification targets of legislators, and the stringent quality requirements of critical automotive applications.

Radiation Hardness of SiC TrenchMOS Devices for Automotive Applications

Stephan Schwaiger

Robert Bosch GmbH

Abstract
The lecture will investigate the cosmic radiation hardness of SiC TrenchMOSFET devices. It will sum up the effect of cosmic radiation on SiC power devices and the way of characterizing the cosmic radiation hardness. We will point out guidelines to improve the cosmic radiation hardness of devices and a method to estimate it in early computational design. Furthermore, we present our experimental results of the investigation of the cosmic radiation hardness of SiC TrenchMOSFET devices. Finally, we will evaluate on the results with respect to the operation of the devices in a traction inverter for electric vehicles in different operations modes.
