Design of a Battery Charge Controller Through MPPT Based Solar Photovoltaic System

Maximum power point tracking system (MPPTs) play a major role in extracting PV power from solar photovoltaic system considering continuous changes of temperature and irradiation conditions. DC-DC boost converter increases the DC voltage from PV system. This paper proposes a maximum power point tracker-based charge controller and obtaining maximum power through a solar photovoltaic system for the battery storage system. DC-DC boost converter is used to enhance the photovoltaic voltage and charge the battery storage system. The results of efficiency, time response and output power are obtained through P&O, incremental conductance, and fuzzy logic control MPPT techniques considering constant irradiance and temperature. Among all three MPPT techniques, the P & O based MPPT Technique with boost converter was found to have better results. In addition, a prototype model of charge controller has been implemented.
