Abstract

To obtain higher DC output voltage, a single-phase boost rectifier adding a capacitor for pumping action in DC circuit is studied. This gives two-stage boost operation by means of inductive and capacitive energy storage/transfer mechanisms under the high-frequency switching. The experimental prototype, employing an insulated-gate bipolar transistor as an active power switching device and a PI controller for output voltage regulation, is implemented to investigate the operation. The experimental results confirm that the input current can almost be waveshaped sinusoidally with a near-unity power factor by the current-mode control.
