Optimal design of switching converters for the integration\ud
and optimal exploitation of renewable energy sources\ud
(RES) represents a crucial issue often debated in the recent power\ud
electronics literature. The design problem required to carry out\ud
a multiobjective optimization characterized by simultaneous conflicting\ud
objectives, such as efficiency, reliability, and price, where\ud
the best compromise solution should be found by the decision\ud
maker among Pareto-optimal solutions. In this paper, a novel\ud
design method for distributed maximum power point tracking\ud
(DMPPT) synchronous boost converter is proposed. The method\ud
is based on nondominated sorting genetic algorithm with the aim\ud
to obtain the best synchronous rectification (SR) boost topology\ud
while considering different targets such as converter efficiency\ud
and reliability maximization, as well as converter price minimization.\ud
New weighted indices are also proposed for a more realistic\ud
characterization of the devices
