In order to increase the high power factor, and acquire the fast dynamic response and the DC power with the steady output voltage, the three-phase voltage rectifier based on SVPWM and DSP is designed. The operation principles of the three-phase VSR and the five-segment SVPWM control strategy are analyzed, and the design of the hardware circuit and the corresponding software of the rectifier are finished. The experiment results show that the rectifier based on SVPWM can availably decrease the harmonic pollution and improve power factor.
