  • Patent number: 11088724
    Abstract: The present technology relates to a communication device, a control method, and a program which enable reliable selection of a desired target. A CLF transmits a polling command received from a NFC reader for selecting a candidate of a final target to targets, selects the candidate of the final target, by setting a P2P application as a target having the highest priority in the selection of the candidate of the final target, selects the final target based on a command other than the polling command received from the NFC reader, and controls to lower the priority of the P2P application, in a case where the P2P application is selected as the candidate of the final target and the P2P application is not selected as the final target. The present technology can be applied to a communication device supporting an NFC standard, for example.

  • Patent number: 11028831
    Abstract: Embodiments herein describe operating a control system for a wind turbine in a first mode and second mode of operation. When in the first mode, the wind turbine provides power to a local AC grid. However, when in the second mode, the wind turbine provides power to a high-voltage direct current (HVDC) link. The control system includes a reactive power control leg and an active power control leg. To switch from the first mode to the second mode, the control system activates a PI controller coupled between the reactive and active power control legs which increases the output voltage of the wind turbine until the magnitude of the voltage activates a diode rectifier and permits the power outputted by the wind turbine to be transmitted along the HVDC link.

  • Patent number: 10050560
    Abstract: An inverter circuit with a current detection circuitry includes a main bridge circuit connected between the pair of DC input nodes, the main bridge circuit converting the received DC voltage to a primary AC current so as to output the primary AC current through an output terminal to be connected to a load; a supplementary bridge circuit connected in parallel to the main bridge circuit between the pair of DC input nodes, the supplementary bridge circuit having a circuit configuration identical to that of the main bridge circuit with smaller circuit parameters in at least some of constituent circuit elements so as to generate a detection-use AC current that is a prescribed fraction of said AC current outputted by the main bridge circuit. The detection-use AC current is detected by a current detector so as to calculate the amount of the primary AC current.

  • Patent number: 9997997
    Abstract: A regulated current-fed power system employs power branching units connected in series. Each power branching unit includes a plurality of parallel-redundant converter groups connected in series with each other within a current path for the regulated current. Each parallel-redundant converter group includes at least two direct current (DC)/DC converters connected in parallel with each other, each sharing the power load. A protection device connected in series with each DC/DC converter disconnects the respective DC/DC converter from the regulated current when the respective DC/DC converter short circuits, with the remaining DC/DC converter(s) then receiving more of the power load. An active clamp connected in parallel with all of the DC/DC converters within a parallel-redundant converter group temporarily sinks a portion of the regulated current when one of the DC/DC converters fails in a short-circuit condition.

  • Patent number: 9991738
    Abstract: One or more techniques and/or systems are provided for providing power to a plurality of dispensers. For example, a supply coupler, such as an alternating current to direct current power converter, is coupled to an energy storage component and/or a load coupler of a power distribution apparatus. The supply coupler provides power over the load coupler to one or more dispensers for operation. The supply coupler provides power to the energy storage component for energy storage. Responsive to a load on the power distribution apparatus exceeding a supply current of the power provided by the supply coupler (e.g., multiple dispensers may attempt to perform concurrent dispense events), the energy storage component may discharge energy to provide additional power to one or more dispensers to facilitate concurrent dispense events. Because the power distribution apparatus may connect to multiple dispensers, a cord management device may be used for power cord management.

  • Patent number: 9979295
    Abstract: A buck-boost DC-DC converter, which includes converter control circuitry, converter switching circuitry, and a first inductive element, is disclosed. The converter control circuitry provides a buck mode timing signal and a boost mode timing signal. The converter switching circuitry provides a switching output signal. During a buck mode of the buck-boost DC-DC converter, when a buck pulse-width of the switching output signal is less than a buck pulse-width threshold, the buck pulse-width is limited based on both the buck mode timing signal and the boost mode timing signal. During a boost mode of the buck-boost DC-DC converter, when a boost pulse-width of the switching output signal is less than a boost pulse-width threshold, the boost pulse-width is limited based on both the buck mode timing signal and the boost mode timing signal. The first inductive element receives and filters the switching output signal to provide a converter output signal.
