Desenvolvimento de um kit didático composto por um conversor CC-CC BUCK para ensino de eletrônica de potência e controle digital de sistemas.

Abstract

This assignment presents the development of an educational kit for Power Electronics and Digital Control formed by a DC-DC step-down converter (Buck), a control and instrumentation board and a gate-driver board to trigger the semiconductor switch (MOSFET) that controls the converter. This assignment has its focus the development of a educational kit that improves the quality of the future engineers by presenting the students with practical classes instead of the standard ones. This project starts studying the topology and operation of the Buck converter so the components can be calculated. Next step is the schematic of the project with the chosen components and the development of the layout for the printed circuit boards (PCB). After we test and make sure all the electronics of the project are working accordingly with the mentioned topology, we start the control design for the two control loops (current and voltage). This design starts with the mathematical model of the chosen control loop. The model has to be validated and it’s used the MATLAB® and PSIM® software for that. After the validation, the control loop is implemented in the implemented PCB and the results are compared with simulated ones.
