The system (100) has a voltage converter (18) converting an input direct current (DC) into an alternating output current, where the converter includes two input terminals (26A, 26B), output terminals (28U, 28V, 28W) and a switching arm (30). A correction device (98) comprises a measuring element for measuring a part of voltage with frequencies preferably less than or equal to 1 Hz supplied by the inverter. The correction device is provided with a calculating element for calculating correction signals (Vuc, Vvc, Vwc) depending on the measured voltage part. An independent claim is also included for a method for controlling a conversion system. |
