Threephase PWM rectifier voltage can be high power factor, DC voltage output stability, good dynamic performance, and can realize twoway flow of energy. Therefore, the field of power electronics has bee the hot issue of research. Firstly, the paper elaborated the basic principle of work for the PWM rectifier according to main circuit topology of threephase voltagetype PWM rectifier. Secondly, the paper proposed the threephase voltagetype PWM rectifier’s control strategy. Based on the control strategy it has studied the space voltage vector pulse width modulation control method as well as designed PI regulator for the threephase voltagetype PWM rectifier. Then, the threephase voltagetype PWM rectifier system simulation, the establishment of the main circuit, the space voltage vector PWM control of the control module and the PI regulator of the simulation model, the threephase voltagetype PWM rectifier simulation of the entire system. Finally, according to the entire threephase voltage PWM rectifier system simulation the article has carried on the hardware and main circuit parameter design. Experimental results show that the paper is designed to achieve threephase voltage PWM converter with high power factor operation, to solve the traditional sense of the rectifier harmonic content present in
