摘要：In predictive direct power control(PDPC)system of three-phase pulse width modulation(PWM)rectifier,grid voltage sensor makes the whole system more complex and ***,third-order generalized integrator(TOGI)is used to generate orthogonal signals with the same frequency to estimate the grid *** addition,in view of the deviation between actual and reference power in the three-phase PWM rectifier traditional PDPC strategy,a power correction link is designed to correct the power reference *** grid voltage sensor free algorithm based on TOGI and the corrected PDPC strategy are applied to three-phase PWM rectifier and simulated on the simulation *** results show that the proposed method can effectively eliminate the power tracking deviation and the grid *** effectiveness of the proposed method is verified by comparing the simulation results.
