Model based design of dcdc converter using AURIXTM Microcontrollers

The thesis project is a model-based design of DC-DC converter of AURIXTM Microcontrollers. As described in the next sections, a step-down converter and the power conversion kit, a kit developed by Infineon, have been used to make the measurements. The goal of the thesis was to create a MATLAB/Simulink model to correctly reproduce the power conversion kit and then generate the controller code automatically via Hardware Support Package to be downloaded directly to the AURIXTM microcontroller using Aurix Development Studio trying to achieve the same results. The benefits of this model-based design, in addition to automatic code generation, are the ability to have everything needed for development in a single package, increasing the speed of development, of prototyping, and reducing the cost of the resources needed for the development and research part. Using this power conversion kit it is possible to use various DC-DC converter topologies such as psfb, llc or dab and it is possible to implement different types of control: voltage mode control, average current mode control and peak current mode control.
