Abstract

EMC filter, for connection between a mains supply network and a mains -operated appliance to reduce conduction noise between said supply network and said appliance, comprising a voltage divider (1030) connected to said mains network, for generating a voltage lower than a voltage of said mains network; rectifying means (1031) connected to an output of said voltage divider, for generating a DC voltage (+Vs, -Vs) ; and an electronic active circuit (201), supplied by said DC voltage (+Vs, -Vs) , for absorbing a noise current transmitted between said supply network and said appliance.
