Research on control strategy of dual-PWM frequency converter

A new dual-PWM converter is introduced because traditional converter has some drawbacks, such as low AC-side power factor, unreversible power flow. By replacing the general inverter 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 improve suggested scheme.
