Abstract Due to the problem that proportional-integral (PI) controller for current loop can not achieve zero-tracking-error in single-phase grid-connected inverter, and that performance of the controller may be affected when there is grid frequency shifting, a novel self-adaptive proportional resonant controller is proposed, which adjusts the resonant frequency point of resonant controller automatically based on a special filter through close-loop control so that grid-connected current can still achieve zero steady-state error when considering grid frequency shifting. Math analysis, simulations and physical experiments validate the validity of the proposed controller..

Key words： Proportional-resonant self-adaptive frequency shifting grid-connected intverter
