Özet
In this article, a novel method is presented for maximum power point tracker (MPPT) system to increase efficiency. For this purpose, maximum power obtained from photovoltaic (PV) panels by pulse density modulation (PDM)-controlled high-frequency series-resonant converter was transferred to grid by a single-phase inverter. The resonant converter and the single-phase inverter circuits used in the system were analyzed, designed, simulated, and implemented. The designed series-resonant converter was operated at resonant frequency for different solar radiation conditions using the PDM control technique, and therefore the maximum power point was tracked. Soft switching was achieved by continuously tracking the resonant frequency. Simulated and experimental results were presented for 600 W prototype by operating the MPPT converter over 100 kHz. The MPPT efficiency was obtained as 99 & x0025; and above. The maximum power tracking of the PV panels was achieved using the perturb and observe (P & O) algorithm with PDM technique. The generated PV power was transferred to the single-phase grid by an LCL-filtered inverter. Proportional integral controller was preferred in the control of single-phase grid-tied inverter.
