A comparative study between photovoltaic pumping systems using a permanent magnet DC motor and an induction motor

Abstract

The solar power source for pumping water is one of the most promising areas in photovoltaic (PV) applications. This chapter presents a comparative study of a PV pumping system driven by a permanent magnet DC motor and one driven by an AC motor. The studied system consists of a PV array, a DC-DC boost converter, an inverter, a motor-pump set, and a storage tank. In addition, we use a maximum power point tracking algorithm to improve the efficiency of the PV system. The comparison was carried out to define the characteristics and the performance of each system. Each subsystem is modeled to simulate the whole system in MATLAB/Simulink. The results obtained from the simulation of the system are satisfactory.
