Abstract

The present invention relates to a driving method for a modular multi-level converter. The driving method include inputting a current reference value (i*) of the upper valve of the modular multi-level converter, measuring a current value (i) of the valve, calculating an error value (err) between the current reference value and the measured current value of the upper valve, measuring a DC link voltage value (V) of the modular multi-level converter, measuring a AC-grid voltage value (E) of the modular multi-level converter, and calculating a voltage reference value (u*) using the current reference value (i*), the measured current value (i), the error value (err), the DC link voltage value (V), and the AC-grid voltage value (E).
