    摘要： A plasma display device includes a plurality of scan lines for selecting a plurality of discharge cells and extending in a row direction. The plasma display device sequentially applies a scan pulse to the plurality of scan lines. The plasma display device calculates a data similarity ratio of two adjacent scan lines by using subfield data of each discharge cell disposed on the two adjacent scan lines among the plurality of scan lines, and overlaps the scan pulses applied to the two adjacent scan lines when the data similarity ratio of two adjacent scan lines is greater than a predetermined ratio.

    摘要： The present invention relates to a multi-pulse HVDC system which is capable of minimizing the number of thyristors by providing a thyristor auxiliary circuit in a conventional 12-pulse thyristor HVDC(High Voltage Direct Current), not using an additional stack of a thyristor and which is implemented based on an auxiliary circuit having a multi-pulse thyristor HVDC system like 24-pulse/36-pulse/48-pulse converters. The multi-pulse HVDC system is characterized in that an upper side thyristor converter 12 and a lower side thyristor converter 13 are installed in a Δ-Δ-Y transformer 11, and two current smoothing reactor 39 and a direct voltage dividing condenser 38 are installed between the upper side thyristor converter 12 and the lower side thyristor converter 13, and two thyristors 32, 33: T2 and T1 are connected to one double winding transformer 31.
