Özet

This paper proposes a new structure for a photovoltaic (PV) simulator. The proposed simulator enables obtaining power-voltage (P-V) and current-voltage (I-V) graphs without the need for a PV panel. The main part of the PV simulator includes series-connected cascaded units, and this feature provides a stepped shape voltage form at the simulator output depending on the unit number. As the number of units is increased, P-V and I-V graphs become more similar to the actual data. Simulation studies were first performed to prove the ability of the presented inverter. Then experimental work was performed to confirm the validity of the simulator. The results show that the presented topology is very convenient for operating as a PV simulator in laboratory environments for researchers. Since the number of units can be increased, the voltage level can easily be moved to higher values and so the simulator can be used in high-voltage PV applications.
