Research of Vector Control of Vienna Rectifier Based on SVPWM

In view of problems of big switching loss and complex control of three-level rectifier, the paper proposed a vector control strategy of Vienna rectifier based on SVPWM. It analyzed working principle of Vienna rectifier and introduced implementation of the control strategy in details. The simulation result showed that Vienna rectifier based on SVPWM has simple control and good dynamic and static performance, whose current of AC side keeps good sine degree.
