  • Patent number: 11404882
    Abstract: A method increases the power of an AC grid by means of the conductors which connect the grid coils of the grid transformer. The conductor-ground voltages and the AC phase voltage are kept lower than a voltage value. The sinusoidal phase voltages of the expanded grid are increased by up to 25% compared to the AC phase voltages, while the phase currents always remain sinusoidal. To this end, the ? generators couple harmonic voltages between the conductors and ground and reduce the amplitude of the resulting hypersinusoidal conductor-ground voltages such that they always remain below the Uix value. In addition, the ? generators control the transferred grid power.
