Abstract
The control device of an electric power converter comprises a control circuit controlling turn-on of power semi-conductor arms. The control circuit comprises a module for determining possible turn-offs of an arm, and a module for selecting turn-offs enabling double switching from among the possible turn-offs. Selection of turn-offs enabling an arm of said converter to be turned off according to the turn-offs enabling double switching in other arms. The electric converter comprises one such control device. The method comprises determination of turn-offs enabling double switching from among the possible turn-offs, and selection of turn-offs to turn an arm of said converter off according to the turn-offs enabling double switching.
