Jae Jun YOU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus and method for controlling compressor
    Patent number: 12018674
    Abstract: An apparatus and a method may control a compressor. The apparatus may control a motor (included in a compressor) such that the motor quickly repeats turn-on and turn-off operations in a cooling power supply time period/section, thereby enabling the compressor to compress refrigerant in the cooling power supply time period/section. Thus, cooling power of a refrigerator may change while the compressor operates with maximum efficiency.
    Type: Grant
    Filed: July 9, 2021
    Date of Patent: June 25, 2024
    Assignee: LG ELECTRONICS INC.
    Inventors: Jinseok Hu, Young Doo Kim, Jae Jun You, Koonseok Lee
  • Method and apparatus for detecting rotor magnetic pole position in a single-phase BLDC motor
    Patent number: 11283379
    Abstract: A method and an apparatus may detect a rotor magnetic pole of a single-phase BLDC motor. The method and apparatus may quickly and precisely initially drive the single-phase BLDC motor by detecting a position of a magnetic pole of a rotor adjacent to a stator by applying a high frequency voltage to the single-phase BLDC motor and analyzing a magnitude of a flowing current.
