I. Introduction
Power converters are required to achieve high efficiency and high-power density. In high current applications, magnetic components are the bottlenecks in increasing volumetric and gravimetric power density. In those applications, ferrous or alloy-based powder cores (hereafter referred to as powder cores) outperform their ferrite counterparts owing to their high saturation flux density, soft-saturation characteristics, and high Curie temperature [1], [2], [3], [4], [5].
