摘要： A composite smoothing inductor that can respond to an increasing demand for downsizing, a higher driving frequency, and the like has a coupling transformer, a first smoothing inductor, a second smoothing inductor on a substrate in a concentrated manner. Two input terminals are connected to the coupling transformer. One output part of the coupling transformer is connected to the first smoothing inductor, and another output part of the coupling transformer is connected to the second smoothing inductor. The first smoothing inductor and second smoothing inductor are each connected to an output terminal. The mutual inductance of the coupling transformer is higher than the self-conductance of the first smoothing inductor and the self-conductance of the second smoothing inductor.

摘要： Certain aspects involve a powered shelf system that can inductively provide power to electrical components of consumer product packages. The powered shelf system can include a housing, a primary inductor, a controller, and a pusher system. The primary inductor can be coupled to or included in the housing. The controller can apply an electrical current to the primary inductor in accordance with a maximum power requirement for the powered shelf system. The applied electrical current can be sufficient to create a magnetic field from the primary inductor that has a minimum field strength at a specified distance from the primary inductor. The minimum field strength can be sufficient to induce a minimum current in a secondary inductor for powering an emitting device that is electrically coupled to the secondary inductor. The pusher system can position the secondary inductor at the distance from the primary inductor.

摘要： A system for omni-orientational wireless energy transfer is described. A transmitter unit has a transmitter resonator with a coil that is configured to be coupled to a power supply to wirelessly transmit power to a receiver unit. A receiver unit has a receiver resonator with a coil coupled to a device load. At least one of the resonators is a non-planar resonator that spans a non-degenerate two-dimensional surface having at least one concave portion.

摘要： An inductor component includes a coil, a magnetic core, a first terminal, and a second terminal. The coil is made of a wound conductive wire. The coil is embedded in the magnetic core made of magnetic metal powder and insulation resin binder. The magnetic core has a bottom surface, a top surface opposite to the bottom surface, a first side surface which is perpendicular to the bottom surface and is connected with the bottom surface and the top surface, a second side surface opposite to the first side surface, a third side surface connected with the first side surface and the second side surface, and a fourth side surface opposite to the third side surface. The first terminal and the second terminal extend from both ends of the coil and protrude from the bottom surface. A line along the bottom surface extending from a position at which the first terminal protrudes to a position at which the second terminal protrudes is longer than a straight line extending from the position at which the first terminal protrudes to the position at which the second terminal protrudes.
