Patent number: 11901832Abstract: This application relates to an active compensating device. In one aspect, the active compensating device includes two or more high current paths through which a second current supplied by a second device is transmitted to a first device, and a sensing unit sensing the first current on the high current paths and generating an output signal corresponding to the first current. The device may also include an amplifying unit amplifying the output signal of the sensing unit to generate an amplified current and a compensating unit generating a compensation current based on the amplified current and allowing the compensation current to flow to each of the two or more high current paths. The device may further include a first anti-disturbance unit connected in parallel to output terminals of the sensing unit, and a second anti-disturbance unit connected in parallel to input terminals of the compensating unit.Type: GrantFiled: October 8, 2021Date of Patent: February 13, 2024Assignees: EM CORETECH CO., LTD., UNIST (ULSAN NATIONAL INSTITUTE OF SCIENCE AND TECHNOLOGY)Inventors: Sang Yeong Jeong, Jin Gook Kim
