Abstract :
In this paper, the control strategy of line voltage sensorless three-phase PWM converter based on virtual line flux is analyzed. A method compensating for the steady-state error of the virtual flux observer is also provided. The simulation results show that the system has good control performance and the proposed method can compensates for the steady-state error of the virtual flux observer.
