A single-phase bidirectional rectifier with power factor correction

A single-phase rectifier based on the conventional two-level full-bridge rectifier and one AC power switch is proposed. The voltage stress of the full-bridge rectifier is equal to the DC bus voltage, but the AC power switch has a voltage rating of half the DC-link voltage. The control signals of the rectifier switches are derived from the voltage balance compensator, current controller and detected operation region of mains voltage. A novel PWM control scheme is proposed to draw a clean sinusoidal line current with high power factor. The three-level PWM pattern is generated on the AC terminal of the adopted rectifier converter by using the proposed control scheme. To verify the proposed operation strategy, performance characteristics are provided by computer simulations.
