Summary
In this paper, the quasi-resonant SEPIC converter topology is evaluated for module integrated distributed maximum power point trackers (DMPPTs) which may increase energy capture from the photovoltaic modules operating with non-uniform irradiation conditions. Operating principals of the proposed module integrated converter is analyzed in steady-state condition and verified by simulation. The maximum converter efficiency is obtained as 94.7%. The advantages, difficulties and zero voltage switching regions of proposed converter are also presented. In addition, DMPPT performance of the proposed converter is evaluated via simulations and the results are presented.
