摘要： A bulk amorphous metal inductive device comprises a magnetic core having plurality of low-loss bulk ferromagnetic amorphous metal magnetic components assembled in juxtaposed relationship to form at least one magnetic circuit and secured in position, e.g. by banding or potting. The device has one or more electrical windings and may be used as a transformer or inductor in an electronic circuit. Each component comprises a plurality of similarly shaped layers of amorphous metal strips bonded together to form a polyhedrally shaped part. 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 for application in power conditioning circuits operating in switched mode at frequencies of 1 kHz or more. Air gaps are optionally interposed between the mating faces of the constituent components of the device to enhance its energy storage capacity for inductor applications. The inductive device 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.

摘要： A filter circuit is used to select frequency bands of digital and analog signals over communications channels in a DSL communications system. The filter circuit includes an inductor having a core that consists essentially of an Fe-base amorphous metal alloy. Advantageously, the filter circuit provides as good or better performance than a filter circuit using a Co-base core; but is much less expensive. As such, it provides a low cost, high efficiency solution to communications applications, such as DSL communications systems, and the like.

摘要： A magnetic core has a toroidal configuration, formed by winding an iron-based amorphous metal ribbon. Thereafter the core is heat-treated to achieve a linear B-H characteristic. Advantageously, the linear B-H characteristic does not change with the level of magnetic fields applied and the frequency utilized. With such properties, the core is especially suited for use in a current transformer.
