Modelagem de uma fonte de corrente contínua controlada utilizando conversor buck

Abstract

Current sources provide the value of current regardless of the load of their connected charge. It has utmost importance for every electrical engineer student, since it is referring to a major subject of graduation. The present study is a characterized as a theoretical complementation of a current source with a buck converter that aims to lower the voltage of the electric circuit. The main goal of the study is to create a source’s prototype for using in lessons at University, in order to develop a microcontrolled current source with a buck converter for didactic purposes. The topology in this study aims to supply a load of 100 Ω, with a current source between 5mA a 1A. The approval of the controlled current source will be performed by software, as Matlab/Simulink.
