REACTOR, AND POWER CONDITIONER APPARATUS

摘要

PROBLEM TO BE SOLVED: To optimally provide magnetic core constitution of a composite magnetic core reactor in combination of a ferrite material magnetic core and a dust magnetic core to reduce reactor copper loss.

SOLUTION: An annular reactor comprises: two facing magnetic core connection parts 12a, 12b constructed with ferrite material; a plurality of magnetic core leg parts 11a to 11d disposed between the magnetic core connection parts and constructed with a pressurized powder body composed of soft magnetic powder and resin; and a coil wound around the magnetic core leg part. The magnetic core leg parts are consisting of a plurality of blocks provided via gaps 13a, 13b, and the gaps are disposed inside the coil.
