Abstract


The performance and efficiency of electric vehicles (EVs) depend mostly on the EVs powertrains. Therefore, one of the most vital research areas is the efficiency analysis of the drivetrain parts in electric vehicles. In this work, two basic drivetrain configurations of EVs are considered and evaluated. Firstly, the one with constant direct current (DC) link voltage and second one having a bidirectional DC-DC converter which supplies variable DC link voltage to the inverter. In order to control a permanent magnet synchronous machine (PMSM), field oriented control (FOC) technique is performed. Furthermore, a bidirectional DC-DC converter with optimized parameters is designed and implemented with variable DC link voltage controller. Finally, a comparison is made taking into account both drivetrain configurations with details efficiency analysis using real time switches at wide operating points of the machine.
