A technique for improving the input current distortion of single-phase boost rectifier with step-up/down operation is studied. By employing the voltage reversibility, capacitor voltage is superimposed upon the supply when the switches are turned on. The arrangement tested, using two insulated-gate bipolar transistors (IGBTs) and a micro computer as a PID controller, is implemented and IGBTs are switched at 20kHz, which is out of the audible band. The experimental results confirm that the input current distortion can be improved with a near-unity power factor.
