  • Voltage converter and display device including the same
    Patent number: 9947285
    Abstract: A voltage converter includes a conversion unit, a self driver and an output unit. The conversion unit includes at least one inductor and provides a boosting power based on an input voltage and a first driving signal. The self driver includes at least one inductor that forms a magnetic coupling with the at least one inductor of the conversion unit. The self driver generates a second driving signal that is synchronized with the first driving signal through the magnetic coupling. The output unit generates an output voltage based on the boosting power and the second driving signal. Switching loss and conduction loss may be reduced by replacing an output diode with an output transistor and voltage spike and electromagnetic interference may be reduced through zero voltage switching. The driving signal of the output transistor may be controlled efficiently by adjusting the inductance of the driving inductor.

  • SPROCKET STRUCTURE OF ENGINE
    Publication number: 20170284530
    Abstract: The present disclosure provides a sprocket structure of an engine including a crank sprocket provided in a cylinder block of an engine and driven by a crank shaft, a high pressure pump sprocket configured to receive rotational force from the crank sprocket through a timing belt, and a cam sprocket having an interior installed on a camshaft and an exterior rotatably coupled to the timing belt so as to be driven. Since a tensioner is fixed in a state in which tension is applied to the timing belt through jigs of the crank sprocket and the high pressure pump sprocket and the cam sprocket having a dual-structure, loss of tension is reduced, thus minimizing occurrence of an error of the timing belt to enhance quality of a product.
