Partial Power Processing Boost Converter with MPPT Control for PV Systems

Nithyashree S | Sumitha T L

Abstract: DC/DC converters which form interface between photovoltaic panels and the batteries/inverters is an integral part of any photovoltaic power plant. These converters regulate the charge provided by PV panels to the batteries/inverters. Therefore in this work, for PV architectures, DC/DC converter with partial power processing technique is proposed. This proposed topology is said to have the advantage of simplicity, high efficiency, low cost and high reliability. The high efficiency of the converter output will be achieved by having the input PV power fed forward to the output without being processed and only a portion of the PV power is processed by the converter depending on the voltage regulation requirement. Here Peturb and Observe MPPT controller algorithm will be used for locating maximum power points, at any sunlight conditions for extracting the maximum power from the PV module and transferring that power to the load. The performance of the proposed topology is analyzed with the help of MATLAB/Simulink model.
