Abstract

This work presents a study on the efficiency of static power converters at partial cascade configuration. In the introduction, a contextualization of the problem is realized, as well the main points to be observed on the design of a practical application of this topology, intended for driver devices for LED lighting. A modeling for the indicated topology is proposed in order to study the efficiency of the pre-regulator and power controller set, which employs non-idealities that represent the real operating conditions. Simulations are performed in order to verify the behavior of the model and analyze the total efficiency. Finally, a prototype is implemented to validate the modeling and observe in practice the performance of the set of converters.
