Classification: CPC H  Y | IPC H

Claim 0:
1. An active compensating device configured to actively compensate for a first current that is input as a common-mode current to each of at least two or more high current paths connected to a first device, the active compensating device comprising:
at least two or more high current paths through which a second current supplied by a second device is transmitted to a first device;
a sensing unit configured to sense the first current on the high current paths and generate an output signal corresponding to the first current;
an amplifying unit configured to amplify the output signal of the sensing unit to generate an amplified current; and
a compensating 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 at least two or more high current paths; and
a first anti-disturbance unit connected in parallel to output terminals of the sensing unit from which the output signal is generated, and a second anti-disturbance unit connected in parallel to input terminals of the compensating unit,
wherein each of the first anti-disturbance unit and the second anti-disturbance unit include a transient voltage suppression (TVS) diode element, and
a junction capacitance of the TVS diode element is several hundred pF or less.
