Extremely Compact Half-Bridge SiC Power Modules Built into EV In-Wheel Motor
Full SiC half-bridge power modules (HPMs) applicable to a real electric vehicle 40-kW permanent magnetic in-wheel motor with an internal diameter of 159 mm have been designed, prototyped and characterized for the first time in the NEDO-SIP program. The prototyped HPMs are extremely compact in size at D35.7×W18.8×H8.0 mm and capable of withstanding junction temperatures up to nearly 200°C. Double-pulse tests revealed that the tested HPM showed steady switching behavior even at 600 V/160 A.
