Study on dual-PWM converter on the basis of space vector control

Abstract：A new dual-PWM converter is introduced because of traditional converter has some drawbacks, such as low ac-side power factor, un-reversible power flow etc.On the base of general converter, by introducing uncontrolled rectifier with PWM rectifier and employing space vector control strategy, dual-PWM converter can actively eliminate ac-side harmonic pollution of inverter, raise ac-side power factor, and work well with steady output voltage and bi-directional power flow.The experiment results are proved correct and feasible.
