MAGNETOELECTRIC DEVICE CAPABLE OF STORING USABLE ELECTRICAL ENERGY

摘要

A magnetoelectric device includes at least one reluctance component, at least one damping capacitor, and a switching circuit. The reluctance component includes a capacitive and inductive magnetic core unit having a loop-shaped first segment and a second segment connected to the first segment, and at least one coil wound around and loosely coupled to the magnetic core unit. The damping capacitor cooperates with the coil to forma resonant circuit. The switching circuit makes and breaks electrical connection between the coil and a DC power source so that an eddy current flowing through the resonant circuit may be generated for storing energy in the damping capacitor.

1. A magnetoelectric device comprising:
at least one reluctance component that includes a magnetic core unit and at least one coil, said magnetic core unit having a loop-shaped first segment and a second segment connected to said first segment, and being made of a magnetic core material such that said magnetic core unit is both capacitive and inductive, said at least one coil being wound around and loosely coupled to said magnetic core unit; at least one damping capacitor coupled to and cooperating with said at least one coil to form a resonant circuit; and a switching circuit disposed to couple said at least one coil to a direct-current (DC) power source, and operable to make electrical connection between said at least one coil and the DC power source for exciting said at least one coil such that said magnetic core unit reaches magnetic saturation, and to subsequently break electrical connection between said at least one coil and the DC power source so as to generate an eddy current flowing through said resonant circuit for storing energy in said damping capacitor.
