| The three-phase voltage-source PWM rectifier is becoming interested in power electronics field because it has many excellent characteristics such as undistorted sinusoidal current waveform, unity power factor, and bidirectional energy flow.A three-phase voltage-source PWM Rectifier system based on digital control chip TMS320F2812 is designed in this paper, and the design of the system structure, the hardware and the software is discussed. This paper analyzes the principle of the three-phase voltage-source high-frequency PWM rectifier in detail. And the rotate reference frame d/q model is discussed through its model in three-phase state reference frame ABC, and then the control strategy is figured out.The theory is feasible through simulation with software Matlab. An experiment establishment is build including main circuit, control board, display board and other equipments required. Digital control method is adopted in the control system. This theory is validated through the experiment.
