Latest Patents

Hasegawwa holds a patent for a bulk amorphous metal inductive device. This device comprises a magnetic core made up of multiple low-loss bulk ferromagnetic amorphous metal components. These components are assembled in a juxtaposed relationship to form at least one magnetic circuit, which is secured in position through methods such as banding or potting. The device features one or more electrical windings and can function as either a transformer or an inductor in electronic circuits. Each component consists of several similarly shaped layers of amorphous metal strips bonded together to create a polyhedrally shaped part. The low core losses of this device, with a maximum loss of about 12 W/kg when excited at a frequency of 5 kHz to a peak induction level of 0.3 T, make it particularly useful for applications in power conditioning circuits operating at frequencies of 1 kHz or higher. Additionally, air gaps can be interposed between the mating faces of the constituent components to enhance energy storage capacity for inductor applications. This inductive device can be easily customized for specialized magnetic applications, making it suitable for use in power conditioning electronic circuitry that employs switch-mode circuit topologies and switching frequencies ranging from 1 kHz to 200 kHz or more.
