Development of a Ferrite Material for Inductive Chargers

摘要

A new ferrite material, 6H40, was developed and its performance verified for use in inductive charging systems. Because the 6H40 surpasses FDK's conventional ferrite materials in magnetic characteristics, it was expected that 6H40 would be useful in automotive DC-DC converters and also in coil products. Super-large pot cores were then manufactured from the 6H40 so that their possible use in the development of fully automated power charging systems for future motor vehicles could be studied.
