Abstract
In this paper the issue of control strategies for single-stage photovoltaic (PV) inverter is addressed. Two different current controllers (the classical proportional-integral (PI) and the novel proportional-resonant (PR) controllers) have been implemented and an experimental comparison between them has been made. A complete control structure for the singlephase PV system is also presented. The superiority of the PR controller is demonstrated with respect to the PI controller in terms of harmonic current rejection and the capability to remove the steady-state error without using the voltage feedforward (VFF). The control strategy was successfully tested on a real 1.5 kW PV inverter.
