An active decoupling device for stabilizing the impedance on an electric line in a determined band of frequency. The decoupling device of the invention is inductively coupled to the power line and comprises a transformer with a primary winding connectable to the power line, and a secondary winding closed on a burden network. In an application, the invention, is used to decouple a smart meter from variations of the load impedance.

Electronic decoupling impedance

Motor drive with a T-type filter with at least two three-phase differential mode reactors and three capacitors, wherein at least one of the three-phase differential mode reactor comprises an auxiliary coil () wound around three wound core elements () such that the common mode current is induced in the auxiliary coil ().

Motor drive with a filter including a three-phase differential mode reactor with common mode damping

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 connected to said mains network, for generating a voltage lower than a voltage of said mains network; rectifying means, connected to an output of said voltage divider, for generating a DC voltage; and an electronic active circuit, supplied by said DC voltage, for absorbing a noise current transmitted between said supply network and said appliance.
