To deal with the synchronization of three-phase grid-connected converters, a synchronization algorithm based on virtual flux orientation is proposed in this paper. By introducing a low-pass filter and a high-pass filter, the orthogonal components of the virtual flux under the stationary coordinate frame that and corresponding to the three-phase voltages can be calculated, and a decoupling compensation is adopted to eliminate the influence of these filters on the fundamental component of virtual flux. Then the phase angle of the three-phase grid voltages can be derived directly according to and , without any rotating coordinate transformation. The simulation results show that this algorithm can extract the phase angle of the fundamental component of grid voltage quickly and accurately under unideal power grid conditions, and it also has strong ability of frequency adaptation.
