| Abstract |
In this paper, three different system topologies for a high performance electric vehicle drive are comparedto each other. Next to the classical three phase permanent magnet synchronous machine in differentconnection schemes, also one topology containing a six phase machine has been included intothe study. Suitable inverter topologies are discussed as well as the design of the multiphase winding ofthe six phase machine. For each of the topologies under investigation, identical types of power semiconductordevices available on the market have been defined as well as an identical active volume ofthe inverter. The three system topologies (three phase single star machine with parallel inverters, threephase machine in H-bridge / six leg connection, six phase double star machine) have been compared toeach other regarding their performance as well as their active short circuit and no-load characteristics.It has been shown by means of simulation that the six phase PSM structure offers some remarkableadvantages with regard to its three phase counterparts which makes it adequate for high performanceelectric vehicle drive applications. |
