Study and design of a resonant LLC converter for the Formula Student Vehicle

The goal of this thesis work is to carry out a preliminary study and design of a prototype of a DC-DC converter that can accept an input voltage range of 400V to 600V and produce an output voltage of 48V with an output power of 1kW. The application is for a prototype Formula Student vehicle. The input of the converter is the high voltage battery of the electric vehicle, while the output is the voltage required to supply the low voltage system of the car. In view of the application, the converter must be designed to comply with competition regulations and must guarantee certain thermal and structural performances. In order to achieve a good efficiency, a resonant LLC converter will be studied and designed, a popular topology that can allow soft switching of the MOSFETs to reduce the overall switching losses. In this thesis, the study will mainly focus on the performance evaluation of the studied topology and the feasibility of realizing the final product, also analyzing the advantages and disadvantages of this solution
