Optimal design of switching converters for the integration and optimal exploitation of Renewable Energy Sources (RES) represents a crucial issue often debated in the recent power electronics literature. The design problem requires to carry out a multi-objective optimization characterized by simultaneous conflicting objectives, such as efficiency, reliability and price where the best compromise solution should be found by the decision maker among Pareto-optimal solutions. In this paper, a novel design method for Distributed Maximum Power Point Tracking Synchronous boost converter is proposed. The method is based on Non Dominated Sorting Genetic Algorithm with the aim to obtain the best Synchronous Rectification (SR) boost topology while considering different targets such as converter efficiency and reliability maximization, as well as converter price minimization. New weighted indices are also proposed for a more realistic characterization of the devices.
