| Abstract: | This paper presents the topological structure and mathematical model of three - phase voltage source PWM rectifier. The design of double closed- loop control system is introduced, and the control strategy of grid voltage orientation and space vector width modulation is adopted. At last, the control system using DSP TMS320F2812 chip is disigned, which achieves the full digital control of rectification. This PWM rectifier could re alize the operation of unity power factor and sine of incoming current that has better static and dynamic characters. |
