Abstract:
Focused on control of three-phase three-switch three-level rectifier ( VIENNA rectifier) with space vector pulse width modulation ( SVPWM) ,a reference voltage assisted sector judgment based SVP-WM method was presented. According to the VIENNA rectifier topology and mathematical model,the re-alization process of conventional SVPWM control method was studied. The relationship of AC side phasor under unity power factor was analyzed and the fixed relationship between current vector and voltage vector was presented. The reference voltage assisted sector judgment based SVPWM control method and its reali-zation process were presented,following the sector division of the voltage space vector plane. Experimen-tal results verified the presented method’s validity and effectiveness. The presented method doesn’t need current sector judgment and simplifies realization process of the control method. Also,the presented meth-od increases the sector numbers of the voltage space vector plane,which improves the current control resolution. This method can be widely used in the input rectifier modules in switch power supplies.
