An AC voltage sensorless predictive current control method for grid-tied inverter with enhanced robustness against current DC offset

Abstract Conventional AC voltage sensorless predictive current control methods for grid-tied inverter are often sensitive to current DC offset errors, resulting in worse control performance. To solve this problem, this paper proposed an improved grid voltage observer as well as a new lumped DC offse...
