Projeto de recapacitação de uma fonte de alimentação estabilizada.

Abstract

The increasing technological growth in microelectronics results in launching sophisticated and efficient new electro electronic products, replacing the current in short time intervals. In parallel, the cost of maintenance and repair of old equipments influences on the decision of replacement, producing stocks of unused equipments, devices and components, however, still capable to perform their specific tasks. Thus, the present work has the goal to recondition a regulated dc power supply, promoting a revaluation on original power components, as the employment of modern equipment In addition, were developed a modern microcontroller-based control system and a protection system to ensure its original operation safely. By means of studies, simulations and testing in laboratory, the proposed systems were physically implemented, in order to obtain a regulated current or voltage in the equipment output.
