Thesis Work - Design analysis & optimization of HV DC/DC converter for 48V applications

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! 

Background 
Volvo Cars commitment in electrification leads us to take the next step in the development of Electric Propulsion Technology - Power Electronics. The Power Electronics department delivers the best-in class inhouse power conversion designs within Electric Vehicle propulsion system such as DC-AC, AC-DC & DC-DC converters. Currently, we are working on our next generation power conversion architectures for future vehicle platforms in order to optimize the efficiency, power density, weight & cost. The traditional automotive LV power supply system is using 12V as a primary distribution and there is a lot of focus in the industry now to move towards 48V LV distribution system. In this regard, we are looking for passionate students who can contribute to the ongoing feasibility study work for HV to LV DC/DC converter design with 48V output using the design simulation tools (MATLAB, PLECS, Python & any SPICE based tools etc.).
 

Scope
Analysis and comparison of power conversion topologies such as circuit design calculations, MOSFET’s power loss mapping, topologies control methods, PWM techniques, circuit modeling and simulations, pareto optimization, lab experiments (if time permits).

Do you fit the profile? 
Students with electrical engineering background with strong first principles design approach in power electronics and good simulation knowledge who like work in advance engineering projects are welcome. 
Students should typically be available partially on-site.

Duration 
•    30 credits/student
•    January 2024
•    Number of students:  preferably 2 students if whole scope is going to be covered

How to learn more and apply 
Selection will be ongoing during the application period, so do not hesitate to send in your application. Attach your CV and personal letter stating your interests within the given area and your thoughts and credentials. 
 

Apply as soon as possible but no later than 19th of October. Please note that applications via email will not be accepted.

We are Volvo Cars

Volvo Cars is a company on a mission to bring traditional car manufacturing into a connected, sustainable and smart future. Since 1927, we've been known for our commitment to safety and for creating innovative cars that make life less complicated. In 2010, we decided to radically redefine our business, resulting in a totally new generation of cars and technology, as well as steady growth and record sales - and we're only getting started. By 2025, we aim to have yearly sales of 1.2 million cars, 50% of which will be electric vehicles and sold directly to customers through digital channels. We also intend to strengthen our position as a modern, progressive employer committed to diversity and gender and racial equality. We believe in the power of people. Join us and be part of Volvo Cars' transformation.
