Photovoltaic grid-connected inverter based on pr control

This paper presents a current control technique for a three-phase grid-connected DC /AC inverter which is used in photovoltaic systems. A Proportional-Resonant (PR) controller is used for replacing the conventional Proportional-Integral (PI) controller in this system. This paper. . Due to the influence of light, temperature, load change and other factors, the traditional grid-connected inverter control method had the disadvantages of slow adaptive dynamic effect and poor stability, and the grid current with high harmonic content brought power quality problems to single-phase. . This paper provides a design procedure of single-phase inverter with LC filter and the inverter load current is regulated by Proportional-resonant controller. [PDF]
