Active compensation device for providing electromagnetic wave noise data

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.

Dependencies are inferred from the claim text.
