MULTI-PHASE-USE MAGNETIC ELEMENT AND PRODUCTION METHOD THEREFOR

摘要

A multi-phase-use magnetic element comprising a plurality of coils embedded in a composite magnetic material, and a negative magnetic flux coupling or a positive magnetic flux coupling present between at least two coils, whereby a multi-phase-use magnetic element such as an inductance and a choke coil suitable for a large-current use in various electronic apparatuses can be downsized further. Such a multi-phase-use magnetic element has excellent ripple current characteristics.
