Abstract
A system for controlling a voltage inverter, or supplying power to a multiphase electric motor of an automobile vehicle, including: a mechanism generating values of power supply voltages for each phase of the electric motor, together with an amplitude value of the power supply voltages; a phase-splicing determination mechanism; and a controller controlling the phase splicing cooperating to control transmission to the voltage inverter of duty cycles generated by determining the duty cycles, as a function of values of power supply voltages for each phase of the electric motor, and also of the amplitude value of the power supply voltages.
