Investigation on modular flyback converters using PI and fuzzy logic controllers

ABSTRACT Modular converters have been drawing more attention in recent years and are widely used in various applications such as undersea observatories, smart grid and telecommunication. Input-parallel output-series configuration of dc-dc converters has dragged much attention in power electronic transformers and photovoltaic systems. In this paper, proportional integral and fuzzy logic controllers are applied to modular flyback converters in an output-series input-parallel configuration and the performance compared. The performance of the controllers is evaluated and the results reveal that the said configuration is viable.
