Abstract: The present disclosure provides an active compensation device for actively compensating for noise generated in a common mode in each of at least two high-current paths. The active compensation device includes: a sensing unit configured to generate an output signal corresponding to a common-mode noise signal on the high-current path, an IC unit that receives the output signal and converts the same into a digital signal, generates noise data and an amplified signal at least based on the digital signal, and outputs the noise data and the amplified signal, and a compensation unit that draws a compensation current from the high current path or generates a compensation voltage on the high current path, based on the amplified signal. The noise data is provided to an external device.

Abstract: The present disclosure relates to an electromagnetic interference (EMI) filter for preventing noise emitted from a power line cable, and an isolated type active EMI filter having no additional elements on a power line. The EMI filter includes a common-mode (CM) choke disposed on a power source side, a Y-cap disposed on an EMI source side, and a sensing winding configured to sense a current. The EMI filter also includes an amplifier configured to amplify the noise current, and a transformer configured to inject a signal of the secondary coil into the Y-cap as a compensation signal.

Abstract: Proposed is a filter module including a filter that filters impurities out in the coolant emitted from a cartridge which includes a housing and a cap. The filter module may include not only a filter accommodation member including a support surface and a perforating member protruding from the support surface but also a first sealing member with a first external diameter including a through-hole fitted into the perforating member. The first sealing member may be transformed into a shape with a second external diameter—the second external diameter is smaller than the first external diameter—corresponding to the width of an inlet of the housing in which the first sealing member accommodates a cap when the cap is perforated by the perforating member.
