  • Photovoltaic system and method of controlling same
    Patent number: 8937824
    Abstract: A photovoltaic (PV) system is disclosed that provides dynamic regulation of the output of a PV array such that the inverter can safely operate without entering a voltage protection mode. The PV system includes a PV array that generates a direct current (DC) output from received solar radiation and a DC link coupled to the PV array to receive the DC output therefrom. The PV system also includes a DC-to-AC power inverter electrically coupled to the DC link to receive the DC output therefrom and invert the DC output to an AC output and a damping circuit electrically coupled to the DC link and positioned between the PV array and the DC-to-AC power inverter. The damping circuit includes a damping resistor and a damping switch.
    Type: Grant

    Date of Patent: January 20, 2015
    Assignee: Eaton Corporation
    Inventors: Jih-Sheng Chen, Hung-Kuang Chen, Jung-Hua Weng

  • Method for processing display data
    Patent number: 8289337
    Abstract: A method for processing display data includes: storing an image data in a plurality of first-type memories by taking scanning line data as a unit; providing one of the scanning line data stored in a particular memory of the first-type memories to one of a plurality of second-type memories, the particular memory being one of the first-type memories, which are not receiving and storing the image data; and outputting the scanning line data stored in the second-type memories. Time periods for outputting the scanning line data of the image data from the second-type memories are not overlapped.
