SYSTEM FOR CONVERTING ELECTRICAL ENERGY SUPPLIED BY A NETWORK AND A CONVERSION METHOD IMPLEMENTED BY MEANS OF SUCH A CONVERSION SYSTEM

This system for converting the electrical energy delivered by a supply network comprises of: a converter and at least one zero-sequence current limiting stage flowing in the converter. The or each limiting stage comprises an active compensation circuit comprising a magnetic component and a voltage source connected to the magnetic component, the voltage source and the magnetic component being adapted to serially inject with the converter an active compensation voltage of the zero-sequence voltages generated by the converter.
