Abstract

A novel stand-alone photovoltaic system topology is proposed in this paper, in which push-pull output circuit is adopted. The system consists of battery array, CUK charger, battery, boost transformation and inverter. Charging strategy based on the battery current regulation principle is adopted in CUK charger, by the way which propsed, a 100% battery state of charge is reached in shorter time. Boost topology using push-pull structure transformation, so that the output from the battery of 24V DC, rose to meet the needs of inverter 380V (bus voltage). System uses closed-loop control, experiments show that the method is simple , effective and flexible, and be able to ensure the stable operation of the system.
