Estudo e implementação de uma plataforma didática e de pesquisa para controle digital de conversores de tensão CC-CA

Abstract

This work presents the development of a didactic and research platform for digital control of DC-AC voltage converters. It is presented a theoretic study about the theme, followed by the project of the platform, which includes the converter, the output filter, the data acquisition circuit and a driver for the semiconductor switches. In addition, a project methodology for a digital PID controller is presented. With this, a projected controller was implemented and the results obtained are compared with those of the computational simulations. All the results are documented, so that the platform may serve as a base for future studies.
