Distributed maximum power point tracking in photovoltaic applications: active bypass DC/DC converter

Abstract

An active bypass structure is proposed to maximize the power production in photovoltaic modules under mismatched conditions. Its efficiency is compared with single and distributed maximum power point tracking solutions based on conventional DC/DC structures. The analysis and simulations performed under realistic assumptions demonstrate the benefts of the novel active bypass converter over solutions based on Boost, Buck or Buck-Boost converters.
