摘要

This paper presents a power inductor with toroid core that utilizes a Permanent Magnet (PM) in its gap (PMTPI) in order to increase saturation current while keeping the same size and inductance. After discussing the PMTPI structure, the results of ANSYS®/Maxwell® physical model simulation results for a design example are presented. The design example considered in this paper is for a toroid-core power inductor with dimensions of 12.5mm × 12.5mm × 6.5mm and inductance of ∼592nH. The saturation current is increased from 14A in the conventional design to 28A in the proposed design.
