Multi-Chip SiC MOSFET Power Modules for Standard Manufacturing, Mounting and Cooling

Taking full advantage of the superior characteristics of SiC Power MOSFETs in the application requires the development of bespoke packaging solutions. Their design needs to thoroughly encompass electromagnetic and electro-thermal aspects to yield major system-level benefits. New design approaches are needed in particular for parallel multi-chip structures at higher voltage ratings. With the aim of enabling full exploitation of the disruptive potential of SiC technology, this paper proposes a review of learnings made in the development of SiC bespoke power modules, focusing in particular on module designs compatible with the most widely established manufacturing, converter assembly and thermal management solutions for large volume applications.
