Si vs. GaN vs. SiC: Which process and supplier are best for my power design?

As silicon (Si), gallium-nitride (GaN), and silicon-carbide (SiC) processes are maturing, so, too, are their suppliers’ expertise and creativity. It is worthwhile to examine the pros and cons of each process, as well as what is unique about the suppliers of the power elements fabricated on these processes. All of these components factor into the decision on the right solution for a particular design. That solution will be a culmination of process maturity and robustness, as well as supplier expertise, support, and capability—and even some intangibles.
