Bulk laminated amorphous metal inductive device |
摘要 |
A bulk amorphous metal inductive device comprises a magnetic core having at least one low-loss bulk ferromagnetic amorphous metal magnetic component forming a magnetic circuit having an air gap therein. The component comprises a plurality of similarly shaped layers of amorphous metal strips bonded together to form a polyhederally shaped part. The device has one or more electrical windings and is easily customized for specialized magnetic applications, e.g. for use as a transformer or inductor in power conditioning electronic circuitry employing switch-mode circuit topologies and switching frequencies ranging from 1 kHz to 200 kHz or more. The low core losses of the device, e.g. a loss of at most about 12 W/kg when excited at a frequency of 5 kHz to a peak induction level of 0.3 T, make it especially useful at frequencies of 1 kHz or more.
