Design of aviation high power factor rectifier based on SVPWM

In order to eliminate harmonic pollution and improve power factor of the rectifier,the control strategy of three phase voltage source PWM rectifier is researched because it has the characteristic such as steady output voltage,unity power factor and so on.The SVPWM control technology is introduced and applied to the design of three-phase aviation voltage source rectifier(VSR) in this paper.The design of AC voltage modulation circuit and DC output voltage circuit and the corresponding software are finished.The experiment results show that the phase of input current is identical with its input voltage,and the rectifier realizes unity power factor by adopting the SVPWM current control technology.
