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 integrated circuit (IC) unit including an amplification unit configured to output an amplified signal obtained by amplifying the output signal, and a digital circuit unit configured to output noise data into which the output signal is digitally converted, and a compensation unit configured to draw a compensation current out of the high-current path or generate a compensation voltage on the high-current path, based on the amplified signal. The noise data is provided to an external device.
