Also useful to reduce drive power in hard-switched field-effect-device cascodes: with some mild tricks, stacked cascodes in particular benefit from compensating miller effect with positive feedback. It still all falls down again when the bottom node/switch is turned back on, and the only arguably difficult part is minimizing the extend of damping needed to prevent the positive feedback from oscillating, like it happily does with inductive load. The approach appears to be of relevance for MVDC power supply applications, as well-compensated capacitances in a stacked cascode can minimize driving/switching power in hard-switched SiC JFET based switches (at around 1~2 kV per JFET, stacked as high as needed), with usefully low loss up to the MHz range of e.g. PWM frequencies. Switched capacitance converters obviate the need for poorly-scaling higher-frequency magnetics, at the mild cost of needing some more switches (only divide-by-2 seems to be truly effective/ideal, while transformers can do arbitrary ratios), and the arguably massive gain of power density reachable in below-substation power classes (pole transformers, up to electric trains, the latter benefitting especially from skipping both the transformer and the AC filtering needs w.r.t. power-to-weight aspects).
