High performance drive for electric vehicles – System comparison between three and six phase permanent magnet synchronous machines

Autor: Döbler, Ralf, Schuhmann, Thomas, Inderka, Robert B., von Malottki, Sicong

In this paper, three different system topologies for a high performance electric vehicle drive are compared to each other. Next to the classical three phase permanent magnet synchronous machine in different connection schemes, also one topology conta

Impact of Overmodulation Methods on Inverter and Machine Losses in Voltage-Fed Induction Motor Drives

Autor: Mahlfeld, Hannes, Schuhmann, Thomas, Döbler, Ralf, Cebulski, Bernd

The modulation methods Space Vector PWM (SVPWM), Discontinuous PWM (DPWM1, DPWMMAX) and six-step mode are investigated in the overmodulation range of a voltage-fed induction motor drive. This area enables an increase of inverter output voltage so tha
