Thesis Work: Performance improvement of Electric Driveline considering different modulation techniques
Thesis Worker at Volvo Cars
Welcome to explore the world of Volvo Cars by writing your thesis with us! As a thesis worker in our organization, you are supported by a supervisor who follows you during your project. All thesis projects are arranged in business-critical areas and therefore you will be able to contribute to our company purpose – providing freedom to move in a safe, sustainable, and personal way – from day one!
The Electric Drive department 97700 at Volvo Cars is proud of being responsible for designing and delivering system solutions and functionality for the inverters, electric machine, and transmission, in our electrified vehicles.
Our vision is to become “Leading in electrification” and we are aiming to contribute to world class energy efficiency, E-machine functionality, sustainability, customer satisfaction and best performance and drivability, to all our future products.
Scope
An improved efficient powertrain system is always of need in an automotive sector. The efficiency of the powertrain is mainly governed by the electric machine and its inverter loss. Different modulation techniques exhibit different capabilities of realizing fundamental voltages and thus, it plays an important role in determining the drive performance. Considering the complexity with different modulation techniques, Space Vector Pulse Width Modulation (PWM), is the widely used modulation technique. This thesis focuses on different modulation techniques such as discontinuous modulation, harmonic elimination etc., to study their impact of electric drive performance.
Use of different modulation techniques might affect differently to the electric machine losses and the inverter losses, but the goal is to enhance the overall drive efficiency.
Activities we foresee that should be done during this thesis work are:
