Abstract
The aim of this paper is the design of an automatic voltage regulator device for regulating the load voltage supplied by solar cells array (SCA). The device contains DC control circuit (DCCC) and automatic voltage regulating circuit.  This circuit senses any deviation of load voltage from that at maximum power point (MPP) of SCA.  As the voltage deviated away from the voltage at MPP, the circuit changes its state.  Then, the operation of the circuit at this instant changes the performance of DCCC triggering circuit.  Consequently, the (DCCC) will return back the load voltage deviated to that equal to the voltage at MPP. Through this paper the proposed construction of the automatic control voltage device is illustrated. Its design procedures as will as its performance are investigated.  The proper operation of the proposed regulator shows that it’s very suitable for coupling with photovoltaic power systems and agricultural loads (DC Irrigation pump).
  In the present paper, a novel circuit, referred to as the generation control circuit (GCC), 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 point tracking, irrespective of the series connected PV module system. In addition, the total generated power is shown experimentally to increase for the experimental set-up used in the present study.
