Abstract: In this study, a Fuzzy Logic Controller (FLC) based technique proposed for solar power generation using boost inverter. A low dc voltage of photovoltaic array are boosted and inverted into a 220 Vrms ac voltage at a fundamental frequency in a single stage. A closed loop FLC technique is proposed to keep the output voltage constant barring various irradiation conditions. Generally, the sliding mode control and feedback control techniques were used for controlling the output of the boost inverter but it involves more complex control theory. The main objective is to reduce the more power stages for converting dc power in to ac power of a Standalone Solar Power Generation System consisting of a Photovoltaic (PV) panel and a boost inverter under various temperature and irradiation conditions. Hence, the proposed control technique is keep constant output voltage with variable irradiations. Therefore the proposed Solar Power Generation System has more desirable features such as low cost and minimum number of switches. The Total Harmonic Distortion (THD) generated by the proposed configuration is quite reasonable. The complete system is modeled using MATLAB/SIMULINK.
