COMPARISON

Battle of SiC vs GaN power modules

Silicon carbide and gallium nitride have remained a trending topic in the industry for about a decade. Experts try to prove one is better than the other, much like a rap battle. One thing is certain: the wideband gap duo has beaten silicon. It is only because silicon is not a true power semiconductor, but SiC and GaN are. The article compares SiC and GaN power modules and pinpoints where each wins.
