Development of low cost high efficient DC-DC converter for photovoltaic system with fast converging MPPT algorithm

This Paper presents Development of Low cost Effective MPPT system with High efficient DC-DC converter under partial shading condition. The power available at the output of photovoltaic cells keeps changing with solar insolation and ambient temperature because photovoltaic cells exhibit a nonlinear current voltage characteristic. A good number of publications report on different MPPT techniques for PV system most of the existing schemes are unable to extract maximum power from the PV array under partial shading conditions. This paper proposes PSO algorithm to track the global power peak under partially shaded conditions. The Proposed MPPT algorithm is developed in Low cost C2000™ Piccolo™ Launch Pad™, LAUNCHXL-F28027 microcontroller. All the observations and conclusions, including results are presented.
