SummarySummary
IGBT is the device of choice for medium power applications
We have not reached the theoretical limit of the fundamental silicon IGBT structure yet even after 30 years of amazing technology advancement!
Still a lot of potential and return of investment in silicon (and BWG) power device research!
Emerging opportunity to push IGBT into megawatt (1-100MW) high power applications
