| titleOfInvention | Compressed powder magnetic core of low loss, and method for manufacturing the same, switching power supply apparatus, oppression type convertor circuit, activ filter, filter and amplification device using it |
| abstract | The temperature interval (ΔTx) of the supercooled liquid represented by the formula ΔTx = Tx-Tg (where Tx represents the crystallization start temperature and Tg represents the glass transition temperature) is 20 K or more, and Fe, Al, P, C, A powder of a metal glass alloy comprising at least one element Q of Si and B and composed of a structure having an amorphous phase as a main phase, a compressed powder core formed by mixing and molding an insulating material, and powder of the metal glass alloy are prepared. And a molding step of forming a magnetic core precursor by compression molding the mixture by adding an insulating material to the powder of the metal glass alloy and mixing the powder, and the magnetic core precursor (Tg-170) K or more ( Tg) By providing a method of manufacturing a compressed powder magnetic core having a heat treatment step of removing the internal stress of the magnetic core precursor by heat treatment at a temperature of K or less, the coercive force is low and the core loss can be made low. . The present invention also provides a switching power supply device, a filter, and an amplifying device using the compressed powder core. |
