Abstract
The aim of this search is the determination of electrical performance of photovoltaic power system connected with a predesigned DC chopper (DCC), which is built in the solar energy laboratory of our electrical department. Mathematical model is built up to define the system operation. Optimum limits of chopping frequency are determined. The effect of load (DC Fan) and insolation level change upon the performance of solar cells array (SCA) arc investigated. In the present paper, a novel circuit, referred to as the generation control circuit (GCC), or DC chopper which enables maximum power to be obtained from all of the PV modules even if some of the modules are prevented from receiving light. The proposed circuit enables the individual PV modules to operate effectively at the maximum power irrespective of the series connected PV module system.
