Multiphase hybrid traction drives for electrical vehicles

Abstract

The prospects for the use of multiphase (i.e. having the number of phases more than four) asynchronous linear and non-linear drives in the field of vehicles were presented and described in a number of papers. However the increase of the phase number of asynchronous electric drive system allows not only to improve a number of its technical-and-economic characteristics, but also to create the hybrid traction drives according to scheme “AC Diesel-generator - Commutator - AC induction motor(s)” which will differ fundamentally from the existing ones, and have more simple design and less energy losses (in comparison with analogous existing hybrid drives). These AC hybrid traction drives of novel type are based on the use of the multiphase Diesel generators and non-traditional controlled multiphase induction motors.
