Abstract


According to estimation of relevant research, Photovoltaic power generation, as one ofthe hot spot of new energy applications, would replace the leading position of traditionalenergy in the electric power market by the middle of the21st century. And even the worldtoday after the main trend in the solar power research is distributed grid solar powergeneration technology, such as the building integrated photovoltaic design (BIPV), it alsodetermines the solar power can be famous everywhere, getting into the large-scale applicationstage. The progress of LED lighting technology, especially the development of white LED,makes the concept of green light root in the hearts of the people. Compared with thetraditional energy, Based on the PV power LED lighting system has obvious advantages, andit can do real green lighting. The ultimate goal of this subject is to make sure the feasibility ofsolar lighting system proven LED dc grid through research, and finally to design a solarpower system with a commercial value for LED lighting to meet the needs of the energyconservation, the grid and building of the combination.Overall, according to the progress of the subject, the subject is divided into threestages:solar battery U-I output characteristics, solar cells most power tracing control researchand solar lighting system of dc transform. All the work contains the establishment of thesimulation model of solar cells on the output of the simulation experiment, setting up theexperiment platform of measurement data, simulating the output characteristics of solar cells.And after comparing and selecting the solar cells most power tracing methods, this paperchose a suitable one, doing improvement and simulation test. Finally this paper choseappropriate dc chopper circuits for the most power tracing control, dc switch control and soon
