DEVICE FOR SYMMETRIZATION AND STABILIZATION OF THREE-PHASE VOLTAGE Russian patent published in 2018 - IPC H02J3/26 

FIELD: electricity.

SUBSTANCE: device for symmetrization and stabilization of three-phase voltage comprises three winding groups of three identical series-connected secondary windings of three single-phase transformers having by one primary winding. On the magnetic circuit of each transformer an additional winding with branches through an equal number of turns is placed, the beginning of the additional winding is connected to the beginning of the primary winding and the beginning of the farthest secondary winding of one of the winding groups. The end, beginning or any branch of the additional winding is connected to the corresponding input phase grip by means of the switching circuit at the signal of the control unit. The end of the primary winding is connected to the zero grip. The number of branches of the additional winding is not limited, and the number of turns should be four or more times smaller than that of the primary winding.

EFFECT: expansion of functionality and improvement of the quality of the device.
