BY COMPARATIVE EVALUATION OF THE STRUCTURE ANDPARAMETERS OF COMPLEX ELECTRICAL TRACTION IGBT-CONVERTER?TWO-PHASE INDUCTION MOTOR FULLELECTRIC

The paper analyzes the structure and parameters of the traction systems: IGBT-converter ? traction electric motors asynchronousthree-phase and two-phase design. The comparative estimation of four variants of structures of hauling electromechanic is produced on five indexes. It is rotined that at identical power of loss in engines at diphasic and three-phase execution also identical. A transformer for a diphasic asynchronous engine has on 35% a less volume and in two times a less loss is in a transformer. The choice of the most effective option.
