Abstract: This application relates to an independent active electromagnetic interference filter module. In one aspect, the filter module includes a first element group including a noise sensing unit provided to sense electromagnetic noise, and a second element group including a compensating unit provided to generate a compensation signal for the electromagnetic noise. The first group and the second group may be respectively mounted on different substrates. According to some embodiments, the filter module can reduce a volume of each element constituting an electromagnetic interference filter module, implement a single modularization of a compact structure. The filter module can also improve electromagnetic interference noise reduction performance and a manufacturing method thereof.

Abstract: 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.

Abstract: In a joint structure of steel beam structure, a bracket is coupled and fixed to the lateral side of a large beam or a pillar and a steel beam is coupled to the bracket such that the steel beam is coupled to the lateral side of the large beam or the pillar. One end of the bracket is coupled to the lateral side of the large beam or the pillar, and the other end is inclined such that the lower part thereof forms an acute angle, wherein a first attachment plate is coupled to the inclined end part of the bracket such that a fixed length thereof protrudes from the upper end of the bracket. The lower part of one end of the steel beam is inclined at an obtuse angle so as to correspond to the other inclined end of the bracket.

Abstract: A low-voltage plasma ionizer is proposed. The ionizer may include a resonator module comprising a metal plate and configured to generate plasma by using an electric field, wherein the metal plate comprises a long side extending in a longitudinal direction, a short side crossing the long side, and a slot extending in the longitudinal direction. The ionizer may also include a source generator connected to the resonator module, and configured to supply a signal to the resonator module to generate plasma including plasma ions around the metal plate. The ionizer may further include a fan placed in an XY plane, and configured to move the plasma ion in a direction crossing the XY plane.
