Boyko A. The Thyristor Voltage Converter - Induction Мotor electric drive with а losses minimization under power supply from source with asymmetrical voltage.

The mathematical models adequate to electromagnetic and electromechanical processes in the electric drive TVC-IM are realized. The improvement of settlement methods TVC-IM break stability system research is executed. The method of stability research based on the analysis of the electric drive various parameters is evaluated and shown. The schemes of a system of automatic symmetrizing of IM stator currents are described, the algorithm and features of management is shown. The modelling of automatic symmetry is carried out and the parameters of its work are determined. The engineering automatic system of losses minimization with simultaneous symmetrizing function was executed. The loss diminution quantitative parameters of the IM potency and symmetrizing parameters for the electric drive power supply from a source with asymmetrical voltage were indicated. The paths of efficiency increase the automatic system of losses minimization at the expense of microprocessor control were illustrated facility application. The research of the current maximum harmonics influence on supply line was conducted.
