Abstract

Nowadays, due to the magnetic materials technology progress new design solutions are provided to engineers in order to develop new supply systems using power converters with high power density and high operating frequency. Planar magnetic structures have multiple advantages as compared to conventional wound technology, being used in supply systems that require low profile magnetic components and high power density. Over time, literature has shown that the losses in planar structures working at high frequency may conduct to important power losses. This paper performs a thorough analysis regarding power losses due to high frequency operation, leading to multiple levels of optimization for a given virtual model represented by a planar ferrite core transformer. Using computational methods a planar transformer model with E+PLT core has been designed to operate at 1MHz. The analysis will be made using the Finite Element Method (FEM) provided by Ansys Maxwell 3D in order to investigate the magnetic density flux distribution in the core and current density in the windings.

平面铁氧体铁心变压器高频功率损耗研究

如今，由于磁性材料技术的进步，为工程师提供了新的设计解决方案，以开发使用高功率密度和高工作频率的电源转换器的新供电系统。与传统绕线技术相比，平面磁性结构具有多种优势，可用于需要低轮廓磁性元件和高功率密度的供电系统。随着时间的推移，文献表明，在高频下工作的平面结构的损耗可能导致重要的功率损耗。本文对高频运行造成的功率损耗进行了深入的分析，并对以平面铁氧体铁心变压器为代表的给定虚拟模型进行了多级优化。利用计算方法，设计了一个工作频率为1MHz的E+PLT铁芯平面变压器模型。分析将采用Ansys Maxwell 3D提供的有限元方法(FEM)，以研究磁芯中的磁通分布和绕组中的电流密度。
