Abstract PWM VSR with sinusoidal input current realizes that power factor is unit. The DC voltage is constant .It can quickly adjust the control.The dynamic performance is good . It can realize two-way flow of energy as well as other significant advantages has been widely attention. PWM VSR is a strong coupling, complicated ,nonlinear time-varying systems. First, typical topology and work principle of PWM rectifier is studied. The mathematical model of single-phase PWM VSR is established and three-phase PWM VSR is studied in ABC coordinate and dq coordinate model. Based on the study of the PWM rectifier control strategy and control system is designed. By constructing simulation model in Simulink environment of single-phase, three-phase.Which prove the feasibility of the control method. Secondly, the main technical parameters of single-phase PWM VSR are given. The design of hardware and software is optimized. On the one hand, the design method of main circuit and power switch tube exchange of type selection is introduced, including the engineering calculation and the design of driver protection circuit, etc.In addition, the indirect current control and direct current control is presented.On the other hand, ARM LPC2131 development board as the controller is used. Software is presented in detail the main program, interrupt service routine, the DC voltage detection module design flow.The control method for the digital implementation. Finally, the single-phase PWM VSR prototype and debug is builded.The experiment under the condition of soft and heavy load is done.Which verify the single-phase PWM VSR the effectiveness of the control method and the engineering design.
