Abstract

Inductors with small footprints and low profile are vital to the development of high density converters with optimal power conversion, inductors that can embedded should be considered as they provide excellent characteristics. This paper investigates a type of planar magnetic inductor which uses magnetic shielding over an air inductor, instead of using a regular core material. A synchronous buck-boost DCDC converter is built to verify the effectiveness of the semishielded inductor compared to the planar inductor. Furthermore, inductance characteristics are investigated, using the MadMix inductor test system
