Abstract

Nowadays, the growth of Module Integrated Converters (MIC) concept is going on increasing. This concept was developed for Photovoltaic (PV) applications to improve the efficiency of the converters. In this paper, the authors have proposed a submodule Maximum Power Point (MPP) tracking algorithm to track the maximum power from the partially shaded cells. Generally, PV module have three submodules. Each submodule is formed by series connection of two strings. Here a different Perturb and Observe (P & O) algorithm is considered for each submodule to track maximum power from the all three submodules. Each submodule will have their own DC-DC converter. In Direct Current (DC) stage, DC-DC converters are connected in three configurations to serve sufficient energy to inverter for single phase grid connected systems.
