摘要： A flywheel energy conversion device provides highly efficient conversion between kinetic and electrical energy. The flywheel produces increased output by providing armature coils in an air gap formed about the flywheel (both radial and axial embodiments are described). In preferred embodiments, field coils of a magnetic circuit are energized with DC drive current that creates homopolar flux within a rotating solid rotor having teeth cut from a flat disk. The total reluctance of the magnetic circuit and total flux remain substantially constant as the rotor rotates. The flux may travel radially outward and exit the flat disk through the teeth passing across an armature air gap. Airgap armature coils are preferably utilized in which the changing flux density (due to the rotating teeth) induces an output voltage in the coils. The flux is diffused before returning to the rotor in one of several ways such that core losses are effectively reduced, thereby enabling the flywheel to operate efficiently at high frequencies.

摘要： A magnetic bearing system has magnets for producing magnetic fields, and a member which carries loop portions of electrically conductive material. The member and magnets are relatively rotatable about an axis of rotation so that the loop portions travel along a prescribed circular path relative to and through the magnetic fields. The magnetic fields subject the loop portions to magnetic flux to produce electromotive forces in the loop portions when the loop portions deviate from the prescribed circular path. This induces an electrical current in the loop portions. The direction of this electrical current is such that, in the presence of the magnetic fields, Lorentz forces are exerted on the loop portions and the loop-carrying member in directions which are lateral with respect to the circular path. To avoid undesired current flow when the member is rotating on its prescribed axis, at least the first and second loop portions are electrically interconnected to form a closed loop. The interconnected loop portions are circumferentially spaced from each other and they lie in circumferentially spaced magnetic fields.

摘要： An alternating current electromagnet is used in a magnetic bearing in which one or more electrically conductive loops travel on a prescribed path through a magnetic field produced by the electromagnet. An electrical current is induced in the loop whenever it deviates from its prescribed path. A power supply drives the electromagnet(s) at a frequency at which the magnetic field interacts with the currents induced in the loop to force a deviant loop laterally toward the prescribed path. Capacitors may be connected in series with the loops to provide them with the desired reactances.

摘要： An approach is provided in which a power design verification system retrieves a power intent data corresponding to a power design, which identifies the power design's power modes and power mode transition conditions. The power design verification system selects one of the power mode transition conditions, which identifies input signals that invoke a transition from a first power mode to a second power mode. In turn, the power design verification system generates simulation stimuli based upon the identified input signals and simulates the power design utilizing the generated simulation stimuli accordingly.

摘要： Discrete, contained charged particle bundles are converted into heat energy for driving a load. In one embodiment the bundles propagate between a cathode and anode in a gap between a pair of solid dielectric members, which gap has a dimension between a pair of facing surfaces of the dielectric members equal approximately to the diameter of a group of such bundles propagating together. The bundles are derived in response to high voltage short duration pulses derived from a modified Blumlein switch. The bundles are periodically derived and converted to current that flows in a circuit having a resonant frequency equal to the frequency of the bundles. In another embodiment the bundles are derived from a cathode including a liquid metal pool in contact with a solid dielectric surface along which the bundles propagate to an x-ray emitting target or an anode that is heated by the bundles, to convert the x-rays into useful emission and/or the heat into useful work.
