Active filter
First Claim
1. Active filter adapted to compensate polluting harmonies on an electricity distribution network and comprising a source of energy, a bridge converter connected between the source and the network, control means for controlling the bridge converter in order to compensate for polluting harmonics, characterised in that the energy source is not changed by the bridge converter such that the state of the energy source is independant of the control means and such that the control means controls the injection of harmonies on the network by the bridge converter independantly of the state of the energy source.

Abstract
An active filter for compensation of polluting harmonics on an electricity distribution network comprising a source of energy (19, 20), a bridge converter (21) connected between the energy source and the network, control means which control the bridge converter in order to compensate for the polluting harmonics, characterized in that the state of the energy source (19, 20) is independant of the control of the bridge converter carried out by the control means (22) and in that the control means (22) control the injection of the harmonic components independantly of the state of the energy source.
