Haha SiC and IGBTs are hardly esoteric. If anything, GaN is esoteric. You just wouldn't know it because industrial doesn't get the same press as computer power supplies.
Thanks! Just a hobbyist, glad to hear industry perspective on this!
Cool. Be safe, don't play with SiC or IGBTs, the high voltage will kill you. GaN will be more mainstream in a few years, Infineon just bought GaN Systems.
