Title:
ACTIVE VOLTAGE COMPENSATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/200054
Kind Code:
A1
Abstract:
The present invention provides an active voltage compensation device which actively compensates for common mode noise generated on each of at least two high current paths. The active voltage compensation device comprises: a sensing unit which senses a common mode noise current on high current paths to generate an output signal corresponding to the noise current; an amplification unit which amplifies the output signal of the sensing unit to generate an amplification signal; an amplification signal feedback unit which transfers a feedback signal corresponding to the amplification signal of the amplification unit back to the amplification unit; and a compensation unit which generates a compensation voltage on the high current paths on the basis of an output voltage corresponding to the amplification signal.
