摘要

With the rapid development of economic, progress of science andtechnology, more and more traditional energy will be on demand , which brings us a series of problems such as energy crisis and environment pollution. As a clear energy, solar energy has been paid attention to and will be a potential one new energy. This paper mainly introduces the independent solar photovoltaic control system, and expounds the charging and discharging control system of the battery and the inverter system. In the controller design part, the PWM inverter control mode is designed by analyzing the characteristics of the solar cell and the battery to charge the battery. The main circuit uses the BUCK circuit to realize the charging control design. In the inverter part, since the design is with DC load, the DC/DC conversion circuit is adopted, and the method of load maximum power tracking (MPPT) is adopted, which has the advantages of rapidity, stability and accuracy.
