  • Patent number: 10150372
    Abstract: Forms of the present disclosure include an input end, and an output end connected to the input end to improve a power factor through the input end. The output end includes non-electrolytic capacitors formed at both sides of an electrolytic capacitor for output, and first inductors formed between the respective non-electrolytic capacitors and the electrolytic capacitor. Therefore, forms of the present disclosure may reduce a ripple current (current stress) at a PFC output end through a CL circuit formed at a left side with respect to the electrolytic capacitor, and reduce an input ripple current (input current stress) of a DC-DC converter through an LC circuit formed at a right side.

  • Patent number: 9884084
    Abstract: The present invention relates to a bone regeneration or bone formation promoting pharmaceutical composition comprising muramyl dipeptide, an analog thereof, a derivative thereof or a pharmaceutically acceptable salt thereof. In contrast to existing passive therapeutic agents which center on bone absorption suppression based on mechanisms for reducing osteoclast functionality, the composition comprising muramyl dipeptide of the present invention promotes the differentiation of osteoblasts, which are bone forming cells, and can advantageously be used in various diseases where bone formation is required as an active therapeutic agent that does not affect osteoclast.

  • Patent number: 9627958
    Abstract: A method for changing a capacitance value of an output capacitor of a power factor corrector (PFC) includes applying AC power to a power conversion circuit. It is sensed whether an instantaneous power failure occurs in the AC power. Output capacitors of the PFC of the power conversion circuit are connected in parallel to each other to increase capacitance values of the output capacitors, when it is sensed that the instantaneous power failure does not occur in the AC power.
