A Built-In High Temperature Half-Bridge Power Module with Low Stray Inductance and Low Thermal Resistance for In-Wheel Motor Application

Abstract:

In order to integrate a five-phase inverter system into the limited space of an in-wheel motor, a high temperature low stray　inductance SiC half-bridge power module with a volume of about 5 ml was designed, fabricated and tested. The stray inductance in the module was calculated by an electromagnetic simulator and confirmed by measurements to be 4.4 nH. Double-pulse switching tests were conducted at temperatures up to 200°C. Thermal resistance, including that of the substrate, was calculated to be 0.153 °C/W. Fast switching capability was accomplished with an external gate resistance of 1 Ω.
