Reator eletrônico microcontrolado de alto fator de potência para lâmpadas de alta intensidade de descarga

Abstract

This work presents an overview about the High intensity discharge (HID) Lamps, showing its operation, the lamps variety and the peculiarities of this drive. The drive with electromagnetic ballast and electronic ballast are studied to verify advantages and disadvantages. After the analysis of electromagnetic and electronic drives, an electronic ballast is proposed. A prototype was implemented to verify the ballast performance. The experimental results have proved the viability of the electronic ballast proposed, emphasizing the reduced number of components used to make the prototype.
