    Just curious... How many companies using IGBT switch mode power supplies in their amps these days? I'm assuming all the ultra-lightweights have switch modes.

    QSC use IGBTs in our switch-mode supplies. I would think it's probably a very common practice, given that there are ICs made specifically for driving IGBTs in switch-mode supplies.
