摘要：
Synchronization with the grid voltage is critical in the control of grid-connected power converters. This paper proposes a phase-locked loop based on reference current. The method introduces a reference current induced by controlling variable parameters PI controller and a low-pass filter. The phase angle of fundamental voltage is tracked at the stability point where the phase angle of reference current leads the fundamental voltage a quarter of cycle. Simulation results are provided to demonstrate its excellent performance, with comparison made to other approach under unbalanced and distorted grid.
