This paper presents mathematical modeling procedure of three-phase grid-connected photovoltaic inverter. Presents synchronous PI current control strategy and the method for adjuster design. The typical waveforms of grid voltage, grid current and harmonics of grid current are carried out on a 100 kW photovoltaic inverter, which can provide some guidelines for engineers to analyze, design and implement.
