Investigation of a Novel Integrated Magnetic System using Finite Element Method in Comparison to Conventional Integrated Magnetic Devices

Abstract

Integration of passive magnetic devices is essential to design highly efficient DC/DC converters. Due to the need for green electronics, but also to save as much space as possible for modern designed devices such as LED TVs and space saving bright LED illumination, the development of such devices is highly necessary nowadays. This paper deals with this multi-physics issue and presents a novel Integrated Magnetic System (IMS), investigated by the Finite Element Method (FEM). Two different FEM approaches are applied to give proof of evidence for the correctness of the analyzed data. Two different kinds of IMS are assayed in this research, one vertical design and one new horizontal configuration. Both magnetic systems are developed with a novel capacitor arrangement to save as much space as possible.
