  • Patent number: 8536722
    Abstract: In a wind turbine generator, the rotation of the rotor is speeded up by a hydraulic pump and a hydraulic motor and is transferred to a synchronous generator. In a state in which the wind turbine generator is interconnected to a utility grid, and the synchronous generator reaches a synchronous speed, if no mechanical power is transferred to the synchronous generator, a wind-turbine control system operates the synchronous generator as a synchronous condenser, thus controlling the magnitude of the field current of the synchronous generator. Thus, the wind turbine generator can supply reactive power to the utility grid without adding new equipment, such as a reactive power compensator using a semiconductor switch.

The slave outlet receives the wireless signal and provides a power supply or stops providing the power supply to the slave device connected to the slave outlet.

  • Patent number: 8536734
    Abstract: An apparatus for inverting DC voltage to AC voltage by stacking of DC voltage sources from a series of DC voltage sources comprises a plurality of circuits. Each circuit includes a first power switch, a second power switch, and a third power switch. The first power switch allows selective connection of adjacent DC voltage sources in the series to provide stacking of DC voltage sources. The second power switch allows selective connection of a first bus to a corresponding location between adjacent DC voltage sources. The third power switch allows selective connection of a second bus to a corresponding location between adjacent DC voltage sources. Controlling the plurality of power switches produces an AC voltage output by coordinating stacking of DC voltage sources and associated connections to the first bus and the second bus.

  • Patent number: 8536738
    Abstract: There is disclosed a system for transferring energy wirelessly by an evanescent electromagnetic field. The system includes a housing including electrically conducting walls defining a space and an injector configured to inject electromagnetic waves into the space. A wall of the housing is configured to be placed adjacent to an electromagnetic energy reception device and includes one or more apertures. The frequency of the electromagnetic waves is lower than the cutoff frequency of the housing, and the one or more apertures have a size smaller than the waves wavelength so that an evanescent electromagnetic field is emitted from the one or more apertures of the wall and may reach the energy reception device.
