Investigations of High Frequency Planar Power Integrated Magnetic Circuits via Finite Element Method

Abstract

High frequency (HF) magnetic devices are often used in many sorts of devices due to their lower construction dimension and high power handling. This paper introduces a new type of HF and high power density planar Integrated magnetic circuit (IMC) developed for a wide range of applications such as power supplies and DC/DC converters. The paper investigates the differences of a planar and a 'Top-Up' IMC version via FEM, introduces the concept of this special combination of inductor, capacitor and HF transformer, and visualized future investigations in the field of these HF high power density magnetic devices.
