An artificial intelligent controller for a Three Phase Inverter based Solar PV system using boost converter

In this paper, the effectiveness of the soft switching control strategies for the Three Phase Inverter based Solar Energy Conversion system with boost converter was explained. The solar irradiation and temperature are mainly depends on the output power produced from the PV conversion process. The Boost Converter is used to obtain the maximum power and is controlled by the Fuzzy logic controller. The Sinusoidal Pulse Width Modulation (SPWM) produces the soft switching control strategy for the proposed topology. The proposed system involves a Stand-Alone Photovoltaic System, Boost converters, Fuzzy Logic Controller, Three Phase inverter and a load. The regulated voltage and current from the boost converter is fed to the inverter circuit which is connected to the load with a continuous maximum power. The fuzzy logic controller is used to improve the boost converter efficiency and the sinusoidal PWM is used to give pulses for the inverter circuit. The inverter output current for driving a load should be noted such that it does not carry the harmonic content. However since disturbed sine wave is unavoidable under various factors it is necessary to reduce the harmonic level to obtain a highly effective output. The results are generated in MATLABSIMULINK and are shown.
