摘 要：A novel stand-alone photovoltaic system topology is proposed in this paper,in which push-pull output circuit is *** system consists of battery array,CUK charger,battery,boost transformation and *** 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 *** 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.
