  • Patent number: 10298144
    Abstract: A power conversion system and a method for voltage change detection, specifically, relates to a detection circuit implemented in the AC-DC power converter, detect the voltage change. The AC input voltage is rectified to convert into a DC input voltage transmitted to a detection unit generating a detection voltage signal at different logical states corresponding to the input voltage changes. A charge current source unit is used for charging the capacitor when the detection voltage signal is in a second state and a discharge current source unit is used for discharging the capacitor when the detection voltage signal is in a first state. A primary comparator compares the voltage changes of the capacitor in the alternating charge and discharge processes with a critical zero potential and outputs a detection signal identifying the changing trend of the input voltage.

  • Patent number: 9124861
    Abstract: The invention relates to a display connector with a 4K image resolution. It primarily comprises a first connector, a second connector and a third connector. The present invention is a connector for a display to support high specification images with quad full high definition (QFHD). The third connector is used to connect an existing video playback device merely having the playback function of full high definition (FHD). Then the FHD image data is upscaled through an electrically connected image upscaling module of the first connector, and QFHD image signals with an ultra-high definition resolution is displayed through an electronic display device. Accordingly, the QFHD image signals with the ultra-high definition resolution can be displayed without upgrading the hardware of the player or computer so as to dramatically reduce the required cost of upgrading the hardware.
