Kit didático para o ensino de eletrônica de potência e controle digital de sistemas

Abstract

This report does a brief introduction on engineering education methods, which concludes that experimental classes are more effective ways of eaching, because it allows the application of the knowledge obtained in classes in a practice way. So, it was developed a didactic kit for learning in power electronics and digital control systems, where it is included a buck converter, a printed circuit board (PCB) for instrumentation and control, here the measurements for voltage and current can be processed for closed loop working. Also, the kit is composed of a gate-driver circuit. For the operation of the kit, it was developed some experiments for the students of Power Electronics and Control Digital Systems. These experiments consist, initially, presenting and describing each item of the buck converter and of the instrumentation and control PCB. The second experiment is where the converter is turned on properly, in open loop, with a variable duty-cycle. In the third experiment, the students will be able to design the converter in some different ways, since the converter is prepared with different combinations of resistors, capacitors and inductors. Another experiment is the mathematical modeling of the converter. Finally, the design of the closed loop control is presented. This will allow the students to have some practical experiences instead of just studying it theoretically.
