Solar Power System

With the background of senous pollntion and energy crisis solar energy is gained attention as a sort of noncontaminative and inexhaustible natural energy So the aurvey, development and application foreground of solar air-condition of home appliance is given and study of solar generator system of home appliance is presented in the paper. First of afl, introduction of basic structure and principle of photo ltaic cell and testing output character is a foundation of whole solar generator system. Because of radomicity of natural sun rays an electrical source which simulates output character of photovoltaic cell is researched and it is an auxiliary source of system. Second, a cuk circuit drived by maximal power point in which power comparing method was applied aazalizes tracing and controlling of maximal power point. After analasis of principle and character of fuzzy logic technique and shortcoming dement a scheme applied fuzzy control technique of maximal po~r tracing is advanced. Dual-direction inveiter in solar generator system is discussed primaxily in theory Finally, solar air-conditior system and power system is connected parally and a great deal of data measured shows energy saving effect.
