Abstract

Soft ferrite magnetic materials are widely used for the design of high frequency magnetic links (HFMLs) for emerging power converter applications. In these power converter modules, the HFMLs are excited by the high frequency inverter outputs. These output signals are typically non-sinusoidal such as square, trapezoidal, and triangular. In this paper, a multi-winding HFML (MWHFML) is mathematically modeled and designed in ANSYS/Maxwell environment. The operating frequency is considered as 100kHz. The MWHFML has multiple inputs and single output terminal connected with load. After simulation, the electromagnetic characterization is performed such as analyzing the load currents, transient magnetic flux density, magnetic flux intensity as well as load profile. The load inductance effects on the magnetic flux density are presented. Ii is recommended that, the characterization would perform imperative part for the advance of competent power converter technologies.

非正弦激励下多绕组高频磁链的电磁特性

软铁氧体磁性材料广泛应用于新型电源变换器高频磁链的设计。在这些功率转换模块中，hfml由高频逆变器输出激励。这些输出信号通常是非正弦的，如正方形、梯形和三角形。本文在ANSYS/Maxwell环境中对多绕组HFML (MWHFML)进行数学建模和设计。工作频率考虑为100kHz。MWHFML具有多路输入和与负载连接的单输出端子。仿真完成后，进行了负载电流、暂态磁通密度、磁通强度、负载分布等电磁特性分析。给出了负载电感对磁通密度的影响。本文认为，该特性的研究将对功率变换器技术的发展起到至关重要的作用。
