    Not… really. Remember the voltage rating increases but the capacitance itself can reduce so the dielectric just increases in size but shrinks in layers. Same energy, but since it’s cv^2 you can actually reduce capacitance more.

    You’re talking about the bulk input tanks which need to be 100v, the rest of them past the inductor should be the same.

    All thus being said, nobody will do this, not for a good reason, the guys who do power circuits think differently than the guys who do logic and their state space equations say it’s not safe, which would be true for reactive loads but for this kind of logic it’s mostly resistive with some obnoxious parasitic inductance and nasty switching noise that the supply caps would filter.

    This is changing with the younger generation who don’t have those prejudices.
