A new modified MPPT controller for solar photovoltaic system

Solar energy is an important alternative out of the various renewable energy sources. This paper presents a new modeling of Maximum power point tracking controller with variable irradiance and variable temperature unlike the existed MPPT controller methods where either constant irradiance or constant temperature are considered as parameters. Using this proposed MPPT controller the parameters such as Power, voltage and current are analyzed using simulation model and experimental validation. This output obtained from the MPPT controller is given to DC-DC boost converter and inverter in order to enhance the output power obtained from the PV array system. The results obtained using the proposed controller is compared with the existed perturb and observe methods.
