  • Patent number: 10386878
    Abstract: A PV module is described with an array of PV cells whereby the module is reconfigurable, allowing different configurations to be applied after installation and during operation, i.e. at run-time. The run time configuration of the module has controllable devices. The main controllable devices are any of (individually or in combination): a) switches which determine the parallel/series connections of the cells as well as hybrid cases also. b) switches between the cells and local dc/dc converters and/or among the DC/DC converters; c) actively controlled bypass diodes placed in order to allow excess current to flow in the occurrence of a mismatch.

  • Patent number: 10381840
    Abstract: A photovoltaic (PV) power station includes at least one AC power production unit. The AC power production unit includes an energy reservoir that is supplied with DC energy from a DC power generator, such as PV panels. The energy reservoir is used as a buffer to store energy, and improve the efficiency of the PV power station. Whether or not an energy reservoir is used, decoupler devices may be used to prevent power annihilation that can decrease the amount of power delivered by the power station to the grid. In system integration for a PV power station, it is found that the declared rating of DC/AC converter in power grid convention should not be taken as the power conversion capability.

  • Patent number: 10374427
    Abstract: The present invention discloses a parameter tuning approach for bypass damping filter to suppress subsynchronous resonance in power systems, namely determining the parameters of capacitor, inductor and damping resistor in BDF. Using this approach, the parameters of capacitor and inductor in BDF can be adjusted, so that the frequency where the negative electrical damping of generator reaches minimum can be away from the frequency range of low frequency oscillation mode and typical frequencies of each torsional mode; the parameter of damping resistor in BDF can be further adjusted so that the minimum value of negative electrical damping is in reasonable range. The application of BDF with parameters tuned by the present invention contributes to the suppression of both the torsional interaction effect and the transient torque amplification effect.

  • Patent number: 10355477
    Abstract: Circuitry and methods are provided that may be implemented to transfer digital signals between multiple voltage domains while some of these domains may be invalid, e.g., such as to transfer a digital signal from a source voltage domain to a destination voltage domain while the voltage of the source domain is zero or invalid. Possible implementations include, but are not limited to, for power selection and distribution in an integrated circuit chip that has multiple power sources (e.g., such as main power supply and a backup power supply), and in which at startup the chip is agnostic of (or is not aware of) which power supply or power supplies is actually powered and available.

  • Patent number: 10355520
    Abstract: Systems and methods for achieving controlled load transition between power supplies and battery units are described. A method may include determining that a Power Supply Unit (PSU) coupled to an IHS via a power transmission interface is turned off; allowing a Backup Battery Unit (BBU) coupled to the IHS via the power transmission interface and in parallel with the PSU via a current sharing bus to supply all current consumed by the IHS via the power transmission interface while the PSU is turned off, where the PSU and the BBU are each configured to output a current sharing signal onto the current sharing bus that is indicative of the PSU's or BBU's current being supplied to the IHS via the power transmission interface; reducing a current sharing scaling factor of the BBU; determining that the PSU is turned back on; and increasing the current sharing scaling factor of the BBU.
