摘要

The method for controlling a rotating electric machine according to the invention comprises a step of controlling the phase currents of the machine by means of a full-wave control (C). According to the invention, the full-wave control (C) is generated via a pulse width modulated signal of which the signal frequency is greater than an electric frequency of the machine. According to another feature, ascending or descending fronts (24, 25) of the pulse width modulated signal are synchronised with first and second crossings of first and second angular switching thresholds (S1, S2) by an electric position (θ) of the machine and a duty ratio (α) of the pulse width modulated signal is periodically refreshed to the signal frequency.
