Using multi‑stage ISOP topologies, Michael de Rooij demonstrates benefits in heat distribution, interleaving for drastic current‑ripple reduction, simpler low-voltage magnetics, lower EMI, and improved conduction losses.
Two high-power converter prototypes (800 V to 12 V and 800 V to 50 V) are detailed, along with practical regulation strategies that minimize penalties in efficiency and power density.
