Single-phase PWM rectifier based on PR controller

摘要：

　　For a three-phase PWM rectifier,the input current signals can be converted to a synchronous d-q coordinate system,and the DC component can be controlled in zero steady-state error by PI control adjustment.But for a single-phase PWM rectifier,it is difficult to achieve this conversion after the pi regulator and to track the zero steady-state error of a given signals sinusoidal current.To overcome these problems,an improved PR controller based on ideal proportion-resonant controller is proposed in this paper.The controller is superior to the PI controller in tracking sinusoidal signals and the DC bus voltage has good stability and anti-interference ability.The MATLAB simulation results verify the effectiveness of the proposed improved PR controller.
