Document Type and Number:
WIPO Patent Application WO/2024/009489
Kind Code:
A1
Abstract:
Provided is a noise filter (100) to be connected to a power line (PL), comprising: a detection unit (120) that detects noise in the power line (PL); a compensation signal generation unit (140) that generates a compensation signal which attenuates the noise; and a compensation signal injection unit (130) that injects the compensation signal into the power line (PL). The output unit of the compensation signal generation unit (140) is connected to the compensation signal injection unit (130). One input unit of the compensation signal generation unit (140) is connected to the detection unit (120) and the other input unit is connected to the output of the compensation signal generation circuit (140). The compensation signal generation unit (140) generates a compensation signal on the basis of the differential signals from the two input units.
