Thesis Work - Design and simulation of low power DCDC for automotive

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! 



Build a SW model with suitable topology that can used to design a low power DCDC. 



In recent years the automotive industry has been moving with fast pace in a new direction of development: electrification. New platforms are seen on the horizon with aim to incorporate the upcoming customer demands. Keeping this in mind, designing and building a prototype for highly efficient micro DCDC (400V to 12V each) with a peak load of 120W. Thermal analysis of the micro DCDC at different load profile.



Perform literature study on the suitable topology that can be used to design DCDC. Investigate on the new type of transistors for example Gallium nitride (GaN) that can be used to increase the efficiency of the overall DCDC. What are the limitations that the industry is facing with silicone-based transistors? Build SW model preferably in PSpice of the DCDC with suitable topology. If the time allows, build a COMSOL models and see the heat dissipation if the DCDC is running on maximum output power and what method can be used for cooling.
