Method for controlling rectifier connected to permanent magnet synchronous generator for providing DC voltage, corresponding device and computer program

The method comprises: determining a first setpoint (Iqref) of a first vector component (Iq) of a phase current (Ia, Ib, Ic) along a first axis (q) of a rotating reference frame (R) connected to a rotor (112) of the generator (108), and a second setpoint (Idref) of a second vector component (Id) of the phase current (Ia, Ib, Ic) along a second axis (d) of the rotating reference frame (R), the phase current (Ia, Ib, Ic) having a first vector component (Iq) and a second vector component (Id); a second vector component (Id) of the phase current (Ia, Ib, Ic) is used to cause a demagnetizing flux of the rotor (112), and the rectifier (118) is controlled as a function of the first and second setpoints (Iqref, Idref) of vector components (Iq, Id) of the phase current (Ia, Ib, Ic). A first setpoint (Iqref) of a first vector component (Iq) of the phase current (Ia, Ib, Ic) is determined by an external feedback loop designed to feedback control the voltage on the DC bus or to regulate the current of a battery connected
