摘要

ELECTRIC CONVERTER AND ELECTRIC CONVERTER COMMAND CONTROLLER, ESPECIALLY FOR INTEGRATION IN AN ELECTRIC VEHICLE. The controller is of the vector-controlled type and comprises means for vector transformation DQ0 (13) of a measured phase current vector (Ia, Ib, Ic) into a transformed measured current vector (Id, Iq, I0), correction means (14d, 14q, 140, 20) of a transformed error vector (Ed, Eq, E0) deduced from a difference between a transformed reference current vector (IRd, IRq, IR0) and the transformed measured current vector, means for inverse vector transformation DQ0 (15) of a corrected transformed error vector (Ed-pi, Eq-pi, E0-T) supplied by the correction means into an error vector corrected (Eabc), and means (16) for generating switching control signals intended for said electric converter as a function of said corrected error vector. According to the invention, the correction means comprise at least one resonant corrector (140) providing a first correction (PR, E0-pr) of an AC component (E0) of the transformed error vector representative of a current of neutral and phase current imbalance.
