Abstract Generating loop current mechanism of photovoltaic grid-connected inverters based on Group control system is analyzed and influent factors of loop current are also derived。Relationship between output power of the inverter and surround current is found by the further analysis. On the base of single grid-connected inverter control method,control system of circulating current restraining method with group control system. Stability of circulation inhibition method is analyzed further. Finally, the control system simulation result and experimental waveforms are given and the theoretical analysis, simulation and experimental results are compared。From the simulation and experiment results, the realizing method and control strategy are entirely correct。
