Abstract

A method for determining a first setpoint for a first vector component of the phase currents along a first axis of a rotating reference frame connected to a rotor of the electric generator, and a second setpoint for a second vector component of the phase currents along a second axis of the rotating reference frame. The second vector component of the phase currents is to bring about defluxing of the rotor; and controlling the rectifier on the basis of the first and second setpoints for the vector components of the phase currents. The first setpoint for the first vector component of the phase currents is determined on the basis of an external feedback loop designed to feedback-control a voltage on a DC bus or to regulate a current from a battery connected to the DC bus.
