Classification: CPC H  G | IPC G  H

Claim 0:
1. An active current compensation device which actively compensates for a noise occurring in a common mode in each of two or more high-current paths, the active current compensation device comprising:
a sensing unit configured to generate an output signal corresponding to a common-mode noise current on each of the two or more high-current paths;
an amplification unit configured to amplify the output signal to generate an amplified current;
a compensation unit configured to generate a compensation current on the basis of the amplified current and allow the compensation current to flow to each of the two or more high-current paths; and
a malfunction detection unit configured to detect a malfunction of the amplification unit,
wherein the malfunction detection unit and at least a portion of the amplification unit are embedded in one integrated circuit (IC) chip.
