Abstract

To fully take the high-frequency advantage of silicon carbide (SiC) devices, this article presents a three-phase integrated power module based on Chip-on-Chip (CoC) structure. The proposed CoC module highly integrates a SiC three-phase bridge and driving circuits, using copper-molybdenum alloy spacer to replace traditional bonding wires, the power loop parasitic inductance is 4.5nH and gate loop parasitic inductance is 2.2nH, reduced by 80% compared with commercial intelligent power module (IPM) and the overall size is only 28.5mm∗18.5mm∗5.5mm. An analytical interference model of the input of integrated gate driver is considered, and proposing a CoC and flip-chip structure to achieve low common-mode EMI and low gate signal interference. The double-sided cooling structure reduces the thermal resistance of both SiC chips and driver chips.
