  • Load symmetrization with controllable inductor
    Patent number: 7259544
    Abstract: A method for compensation and symmetrization of a three-phase system with a single-phase load is provided. At least one variable inductor for connection to the three-phase system is employed in the method. The inductor's inductance is adjusted to obtain a resistive single-phase load and/or a three-phase load which draws balanced line currents. A device and a system for compensation and symmetrization by means of variable inductors is also provided.
