Charging of PV battery at constant current mode by using fuzzy logic control

In this paper PV (photovoltaic) controller system and method of controlling of the buck and boost battery charger is given. The controller is mainly designed to charge the photovoltaic batteries in the mode of preserving the constant charging current. The control system is based on the “fuzzy logic” technique. The simulation results are presented as time waveforms, mainly. Finally, one suggested future possibility to improve this solution.
