RESUMO

Programmable logic devices were introduced about fifteen years ago and nowadays they are used in areas like Telecommunications, Instrumentation and more recently Power Electronics. This work presents the application of an FPGA device in the control of a ballast circuit for driving high intensity discharge lamps. The electronic ballast presents improvements regarding the previous electromagnetic reactors, due to their small size and weight and also because they guarantee a longer life time for the lamps. In order to test and verify the proposed control strategy, a prototype was built to drive 70W,150W and 250W metal halide and high pressure sodium lamps. Beyond the vantages above mentioned, the prototype also presented a notable reduction in the time needed for the lamp to achieve maximum brightness, in comparison to magnetic reactors.
