Abstract :
A sliding mode controller for the single-phase grid-connected photovoltaic system has been proposed in this paper. The system consists of maximum power point tracker (MPPT) controller and Inverter, Which inverts the voltage of photovoltaic batteries to standard sinnsoidal single-phase AC voltage (220 V,50 Hz). Furthermore, it ensures that the output current and power network have the same frequency and phase. They show the robust tracking property against modeling uncertainties and parameter variations. The mathematical modeling is developed and the experimental results verify the validity of the proposed controller.
