摘要： A controller for a semiconductor switch is described that includes a transmitter and a receiver that communicate across galvanic isolation using an inductive coupling. An example controller includes first circuitry referenced to a first reference potential, second circuitry referenced to a second reference potential and galvanically isolated from the first circuitry, and an inductive coupling galvanically isolating the first circuitry and the second circuitry. The inductive coupling includes a first winding referenced to the first reference potential and a second winding referenced to the second reference potential, wherein the first circuitry includes signal reception circuitry coupled to the inductive coupling, wherein the signal reception circuitry includes one or more signal receivers coupled to the first winding to receive signals transmitted over the inductive coupling.

摘要： A magnetic isolator includes a dielectric film having a layer of electrically-conductive soft magnetic material bonded thereto. The layer of electrically-conductive soft magnetic material comprises substantially coplanar electrically-conductive soft magnetic islands separated one from another by gaps. At least some of the gaps are filled with an inorganic dielectric material. The gaps at least partially suppress electrical eddy current induced within the layer of soft magnetic material when in the presence of applied external magnetic field. An electronic device including the magnetic isolator and a method of making the magnetic isolator are also disclosed.

摘要： Various embodiments of a wireless connector system are described. The system has a transmitter module and a receiver module that are configured to wirelessly transmit electrical energy and/or data via near field magnetic coupling. The wireless connector system is designed to increase the amount of wirelessly transmitted electrical power over a greater separation distance. The system is configured with various sensing circuits that alert the system to the presence of the receiver module to begin transfer of electrical power as well as undesirable objects and increased temperature that could interfere with the operation of the system. The wireless connector system is a relatively small foot print that is designed to be surface mounted.

摘要： An electromagnetic resonant coupler includes an input line to which a transmission signal is input; a first resonance line connected to the input line; a second resonance line opposing the first resonance line, the second resonance line undergoing resonant coupling with the first resonance line to thus wirelessly transmit the transmission signal between the first resonance line and the second resonance line; an output line connected to the second resonance line, the transmission signal being output through the output line; a coupling line that electromagnetically couples with at least one selected from the group consisting of the first resonance line and the second resonance line; and a terminator connected to one end of the coupling line.

摘要： A method is provided introducing a phase offset between signals applied to antenna ports of an antenna having multiple antenna elements, such that a first signal applied to one of the antenna ports operatively coupled to one of the antenna elements has a different phase than a second signal applied to another one of antenna ports operatively coupled to another one of the antenna elements to obtain an antenna pattern control. A reduced power is used that is lower than the power used in a non-pattern control operation of the antenna such that a wireless link performance criteria is met with equipment at a far-field point using the reduced power compared to the non-pattern control operation, thereby reducing near field radiation.

摘要： Techniques for duplex communication and power transfer across an isolator are provided. In an example, a first transceiver coupled to a firs-t side of an isolator can include a transmit modulator configured to receive first data and timing signals, to provide control signals to oscillate an output of the transceiver to transmit power and to order each half-cycle of an oscillation cycle of the output to transmit the first data. A second transceiver coupled to a second side of the isolator can include a receive detection circuit configured to compare a received oscillation cycle with a plurality of thresholds and to provide a plurality of comparator outputs indicative of reception of the positive half-cycle and the negative half-cycle, and a receive decoder configured to identify the order of half-cycles and to provide an output indicative of logic level of the first data.
