<p>1. A method for regulating the supply of a multiphase asynchronous motor (M) taking into account the state of charge of a motor for adjusting the control signals of the switches (I1 to I6 ) of a multiphase bridge across the terminals of which the motor is connected, in which the control signals of the switches of the upper and lower paths, for the two respective arms of the same phase of the bridge, are identical and shifted by 180 , have an angle of flow (A1 to A6 ) comprised between 120 and 180 ; and are modulated (mod 1 - 3 - 5, mod 2 - 6 - 4) on 60 electrical degrees of their angle of flow, by a signal (171) the frequency and cyclic ratio of which are depending, on the one hand, on a reference voltage (18) and, on the other hand, on a feedback signal (161) representing the image of the electromotive force as measured across the terminals of two phases (UV) of the motor, the value of said electromotive force being multiplied by a coefficient -k during the time interval comprised between the middle of the interval defined by the angle of flow of the lower path control associated with said motor phase and the middle of the interval defined by the angle of flow of the upper path control associated with the motor phase ; and by a coefficient + k during the time interval comprised between the middle of the interval of the angle of flow of the upper path control of the motor phase and the middle of the interval of the angle of flow of the lower path control for said same phase.</p> |
