  • Patent number: 11949340
    Abstract: A conversion device includes a primary side circuit, a secondary side circuit, a transformer, and a control circuit. The primary side circuit includes a primary side switch and is configured to receive an input voltage. The secondary side circuit outputs an output voltage to a load. The transformer comprises a primary winding and a secondary winding, the primary winding is electrically coupled to the primary side circuit and the secondary winding electrically coupled to the secondary side circuit. The control circuit is configured to control a peak value of the current of the primary side switch, to be limited in a band range.

  • Patent number: 9076055
    Abstract: A detecting system and method suitably used on a production line are disclosed, where a sensing device is arranged on a fixed position of a conveying belt, an image acquiring device and a bar code reading device are vertically arranged above the conveying belt, respectively, a computing device calculates a picture acquiring time of the acquired picture comprising a detection printed circuit board (PCB) acquired by the image acquiring device, and the computing device calculates a position to be moved by the bar code reading device to control the bar code reading device to move and read the production serial number of the detection PCB, whereby a corresponding detection drafting is queried according to a production serial number and optically detecting the detection PCB according to the detection drafting. By means of the above technical means, the detection PCB may be detected on the production line, and thus promoting the production efficiency and detection efficiency of the detection PCB.
