Power electronics today are limited by the magnetic components, which are difficult to scale to high frequencies (HF: 3-30 MHz) and small size. Inductor structures using flux shaping, quasi-distributed gaps, and modular construction can achieve low loss at HF, but for widespread adoption, such structures must achieve low loss across applications and be produced economically. This work demonstrates that a proposed inductor structure with the listed design features can cover a wide application space with only a few sets of manufactured core pieces. Core sets can be scaled by 4x in volume, compared to 2x scaling in conventional core sets.
