Title:
ACTIVE COMPENSATION DEVICE PROVIDING ELECTROMAGNETIC WAVE NOISE DATA
Document Type and Number:
WIPO Patent Application WO/2022/255828
Kind Code:
A1
Abstract:
The present invention provides an active compensation device that actively compensates for noise generated in a common mode on each of at least two high current paths. The active compensation device comprises: a sensing unit that generates an output signal corresponding to a common-mode noise signal on the high current path; an IC unit comprising an amplification part that outputs an amplification signal obtained by amplifying the output signal, and a digital circuit part that outputs noise data obtained by digitally converting the output signal; and a compensation unit that draws a compensation current from the high current path or generates a compensation voltage on the high current path on the basis of the amplification signal. The noise data is provided to an external device.
