Resumen:
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.
