A CONVERTOR FOR ELECTRIC FEEDER AND/OR SUBSTATION FOR RECUPERATING THE BRAKING ENERGY

The invention relates to an electrical converter (30) for a power supply substation of an electrical network and/or for recovering braking energy from railway vehicles traveling on a railway track, the substation being connected to a power supply line capable of supplying a direct voltage to the railway vehicles traveling on the railway track, the substation comprising an electricity distribution network capable of delivering a three-phase voltage corresponding to three phases, the converter (30) comprising a transformer (306) capable of controlling the value of the three-phase voltage delivered by the electricity distribution network, a filtering device (304) capable of filtering the three-phase voltage of the transformer (306), and an inverter (302) connected to the filter (304).
