Active current compensation device capable of detecting malfunction

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;
• a power management unit configured to receive a first voltage from a power supply for supplying power and convert the first voltage into a second voltage having a specified magnitude;
• an amplification unit driven by the second voltage and configured to amplify the output signal to generate an amplified current;
• and
• a compensation unit configured to generate a compensation current on the basis of the amplified current and allow the compensation current to flow to the each of two or more high-current paths,
• wherein active elements included in the amplification unit and active elements included in the power management unit are embedded in one integrated circuit (IC) chip.
