Abstract

The invention relates to a charger for electric vehicles, comprising: two cables, a current transducer disposed on a first cable, and a differential current transducer between cables. According to the invention, at least one of the transducers is an alternating and direct current transducer comprising an oscillator, a symmetry detector and a winding disposed on a first magnetic core, said first magnetic core being disposed around the first cable. The oscillator generates an electric signal by means of the winding at the saturation frequency of the first magnetic core. The symmetry detector comprises a signal generator that generates a signal as a function of the symmetry changes in the saturation of the first magnetic core.
