METHOD FOR CONTROLLING AN INVERTER DEVICE, AND ASSOCIATED CONTROL DEVICE

The present invention relates to a method for controlling an inverter device having six branches (B1...B6) supplying power to a double three-phase machine (3) comprising three first windings (R, S, T) and three second windings (U, V, W), one first winding (R, S, T) being respectively adjacent to a second winding (U, V, W), the method comprising the following steps: - the commands to be applied to the branches of the inverter device are determined as a function of the desired operating point for the machine (3) by a pulse width modulation in which the pulses applied to the different branches are temporally centred relative to one another, - from the determined commands, the commands for allowing at least one branch (B1, B2, B3, B4, B4, B5, B6) to be blocked are determined by varying, proportional to the pulse widths, the commands associated with the three first windings (R, S, T) and to the three second windings (U, V, W), - selecting the combinations of commands allowing two adjacent branches to be blocked, - and applying one of the selected combinations.
