Ensaios acelerados em conversor estático de energia CA/CC trifásico

Abstract

The development process of new products requires their reliability to be compatible with their total aggregated cost. To quantify such reliability, accelerated tests are usually employed. However, there are innumerous factors to be accounted for and the costs associated with such activities must be kept to a minimum. This work intends to describe the experience of accelerated testing on an AC/DC voltage converter, a power supply, from planning to conclusion, sharing mistakes and good practices to contribute with the efficiency of other’s works. Information regarding test infrastructure are also shared, because those directly affect costs and data quality. Some life-stress models frequently used for continuously used electronics were described. It was possible to obtain some indication that the product might achieve a reliability goal of 90 % in 13 years. Some future work opportunities were also identified, adding different tool to improve the quality of the results.
