Kit experimental de conversores CC-CC controlados através de interface USB utilizando software livre sob GPLv3

Abstract

Lessons in the classroom can often not given sufficient time to teach students the necessary practice for learning. Toward that lack of time, a kit that can generate pulses for different dc-dc converter is made in order to facilitate learning and to assist the teacher. And how it will be better if this kit is controlled by a computer, catching the student's attention by the use of modern tools that are used in their day-to-day, all through USB (Universal Serial Bus) communication, present on most computers produced since ten years ago. The project also encompasses the whole concept of free software, bringing an open tool, written in a high level language called Python, with source codeavailable so that anyone can contribute to the work. In the study all the required steps to build the kit are shown, divided into three stages, hardware, firmware and software.
