Comparative Analysis of Magnetic Components for High Power Density Applications

This article presents a comparative analysis of the main characteristics of three innovative magnetic components—Sendust, FluxSan, and nanocrystalline—used for the design, construction, and implementation of high-power-density inductors in a 2 kW three-phase active rectifier. A methodology based on previous studies is proposed, which includes mathematical designs of the inductors, finite element simulations, and iterative evaluations until an optimal design is obtained. During the study, key parameters such as inductance, operating frequency range, power, permeability, maximum flux density, geometry, and current density are evaluated, as well as power losses, volume, and weight. Photographs of the physical construction of the Sendust and FluxSan cores, along with their corresponding windings, are also shown.
