Abstract
The invention relates to an active filter device for a power supply comprising a source having a source of current iS and a voltage VE, a power converter presenting an input inductor L, a power switch T controlled by a chopper signal and delivering an output voltage VS, and a load, the device being characterized in that it includes an active filter converter (10) for generating at its output a compensation current minus harmonics of the source current due to the chopping, in response to an input signal representative of the chopping of the power converter.
