摘要

本文提出了一种环形磁芯功率电感，在其间隙中加入永磁体(PMTPI)，以在保持相同尺寸和电感的情况下增加饱和电流。在讨论了PMTPI结构的基础上，给出了ANSYS®/Maxwell®物理模型的仿真结果。本文所考虑的设计实例为尺寸为12.5mm × 12.5mm × 6.5mm，电感为~592nH的环形铁芯功率电感。饱和电流由传统设计的14A提高到28A。

Permanent Magnet toroid power inductor with increased saturation current

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.
