Implementation of DC-DC Boost & Luo Converters for Photovoltaic Applications

Renewables are eco-friendly, of them solar photovoltaic (PV) systems are growing in popularity as a means to directly transform solar radiation into electricity. Installing a PV array is simple, and the ongoing decline in the price of PV modules provides a support as renewable energy source. As the globe continues to deplete its fossil fuel reserves, discussions about alternative, renewable energy sources are heating up. Due to its quiet operation, low maintenance requirements, and lack of emissions, the photovoltaic (PV) power system is quickly rising to the top of the renewable energy industry. Since a PV array is an expensive system to build, it is necessary to exploit all of the available output power. In this proposed system a comparative analysis between boost and LUO converter has been implanted, for attaining high output gain performance devoted to supply both linear and non-linear loads. The proposed scheme tracks Maximum Power Point (MPPT) from the solar panel by perturb and observe(P&O) and Incremental conductance method (INC). A comparative analysis is performed to attain maximum output. Based on the comparison the converter with maximum output voltage is considered as LUO converter. Finally, a hardware prototype using DSPIC30F4011 microcontroller is considered to validate the performance of the two converters.
