With the increasingly prominent energy crisis and environmental pollution caused by automobiles, the solar energy, as a new and clean energy, has attracted much attention. In this paper, a novel topology of hybrid generator with a PV energy conversion system with a battery in a DC-coupled structure is adopted to solve the problem and replace Fuel Cells, which have important diesel fuel consumption and high energy costs. In the proposed system, the PV Source represents the main source, the DC link and battery the transient power source. This latter can absorb or supply power peaks. Finally, the proposed system is verified by the results of simulation. Copyright (C) 2015, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
