Projeto de um conversor CA/CC não isolado.

Abstract

This paper looks forward to model an AC/DC electric converter non isolated in order to compose a course conclusion paper. The converter to be modeled must be able to work properly under direct electrical network supply, either with a transformer or transformerless. A literature review of the concepts utilized on the addressed circuits will be presented. The modeling will be made by showing functional circuits that accomplish the required activities of the converter arrangement. The choice of the topologies will be made by presentation and the needs required by the converter, which will be then simulated on computer software and experimentaly assembled in a laboratory in order to verify the differences between the controlled and uncontrolled operation modes. The converter will be modeled by join the mentioned circuits such that their combination result in the right operation according to the project requirements. The results of the simulations and the measurements acquired during the assembly will be shown at the end of the paper.
