  • Driving apparatus and method for modular multi-level converter
    Patent number: 9350270
    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*pj2) of the upper valve of the modular multi-level converter, measuring a current value (ipj2) of the valve, calculating an error value (errpj2) between the current reference value and the measured current value of the upper valve, measuring a DC link voltage value (Vdc2) of the modular multi-level converter, measuring a AC-grid voltage value (Esj) of the modular multi-level converter, and calculating a voltage reference value (u*pj2) using the current reference value (i*pj2), the measured current value (ipj2), the error value (errpj2), the DC link voltage value (Vdc2), and the AC-grid voltage value (Esj).
