ZVS (not ZCS) topologies that use planned stray inductance and WBG transistors and class 1 ceramics can operate at 10s of MHz with less than 1% of loss per volt

ZVS (not ZCS) topologies that use planned stray inductance and WBG transistors and class 1 ceramics can operate at 10s of MHz with less than 1% of loss per voltage halving. They have insane power density and lack of wound inductors means there's nothing that causes problems as you push into the kilovolts. But really they're just more efficient (integer ratios, where `n-1` not prime) than classical Buck/boost topologies.
