摘要:The paper presents a successful design and good result of grid voltage feed-forward control strategy with no damping regulator of LCL filter applied in Three-phase Pulse Width Modulation(PWM) rectifier under unbalance grid condition for renewable energy processing. It is demonstrated that the closed-loop current control is decoupled with the grid voltage feed-forward control, and good waveform of grid current with low order harmonics is obtained under unbalance grid condition. This novel strategy is simple and reliable, applied with PI regulator but no resonant controller in   ,    two-phase stationary frame. Moreover, the results of experiment and simulation are also illustrated to validate the novel strategy well applied in the closed-loop current control system under unbalanced grid condition.
