Using of Frequency and Pulse Width Modulation Techniques to Design Load Controllers Supplied by Solar Cells Array.(Dept.E)

The aim of this paper is to design a load controller coupled with a photovoltaic power system. The controller interfaces between the energy storage element (lead acid battery) and the load. The controller is designed using tivo techniques, the frequency and pulse width modulation technique. The design procedure of the proposed controller using cach technique is briefly illustrated. The electrical behavior of each controller is experimentally investigated.
