Title:
ACTIVE COMPENSATION DEVICE FOR PROVIDING ELECTROMAGNETIC WAVE NOISE DATA
Document Type and Number:
WIPO Patent Application WO/2023/055156
Kind Code:
A1
Abstract:
The present invention provides an active compensation device for actively compensating for noise generated in a common mode on each of at least two high current paths. The active compensation device comprises: a sensing unit for generating an output signal corresponding to a common mode noise signal on the high current path; an IC unit, which receives the output signal and converts same into a digital signal, generates each of noise data and an amplification signal on the basis of at least the digital signal, and outputs the noise data and the amplification signal; and a compensation unit for withdrawing compensation current from the high current path or generating compensation voltage on the high current path on the basis of the amplification signal. The noise data are provided to an external device.
