Solar energy is a clean energy and it is increasingly being used all over the world. In this study, a water pump drive has been designed with a switched reluctance motor (SRM) to be powered by a photovoltaic energy source (PV). A boost converter has been used to increase the voltage of the PV source. The mathematical model of the system has been composed in the Matlab/Simulink and simulation results have been obtained. Output voltage of the boost converter has been controlled by using a PID controller at 50 kHz switching frequency. A centrifugal pump has been used as the water pump. In the control of boost converter, an eight bit PIC16F877A microcontroller has been used. The electrical energy obtained by PV panels has been stored in batteries. Battery charge testers have been used in order to control the battery charge level. The speed and current control of SRM has been done by using DS1103 Ace kit. The value of the current has been perceived by using hall sensors and transferred to the digital signal processor by using an analog to digital converter. The accuracy of simulation results has been proved by experimental results.
