A method for controlling switches of a current rectifier installed on a motor vehicle, including: determining a neutral point current intensity required at an output of the rectifier; determining current vector coordinates making it possible to obtain the neutral point current in a Fresnel space including six sectors defined by six remarkable vectors; determining a half-sector including the current vector among twelve half-sectors forming the Fresnel space; determining a weighted vectorial combination of two remarkable vectors defining the Fresnel sector making it possible to obtain the current vector; switching the current rectifier switches to obtain the current vector in accordance with the weighting coefficients; and obtaining a free-wheel vector for remaining time of a cutting period minimizing voltage differences between the ground and the voltage rectifier during transition from one switching to another.
