Sažetak

This paper deals with a simple and efficient control for a standalone photovoltaic (PV) water pumping system based on a separately excited DC motor drive. The structure of this system uses two power converters coupled by a DC-bus capacitor. The first is a DC-DC boost converter used to extract the available maximum power of the PV array by using a perturb-and-observe maximum power point tracking (P&O MPPT) technique. The second is a DC-DC buck converter used as an interface to supply the armature circuit of the DC motor with a variable voltage according to the produced PV power. In order to ensure a constant magnetic flux, the field circuit of the DC motor is connected to the DC-bus capacitor and the DC-bus voltage is regulated at a desired level. The main advantage of this structure is that the features of an expensive permanent magnet DC motor can be achieved by using a low cost separately excited DC motor. The usefulness of this system is verified by a digital simulation using Matlab/Simulink and experimentally confirmed by a real-time implementation based on dSPACE 1104 system card. The illustrated results show a good agreement between simulations and experiments for various operating conditions.
