The method involves connecting a converter unit (1) provided with controllable power semiconductor switches to an electric alternating current network (2). The switches are controlled by a control signal (S) formed by reference currents (u`Na, u`Nb, u`Nc). The currents are formed from a periodic modulation index and a periodic modulation angle. The index and the angle are formed from d-components of Park-Clarke transformation of positive and negative sequences of phase currents and from q-components of the transformation of positive and negative sequences of other phase currents, respectively. |
