単相二段昇圧形整流器の入力電流歪みの改善 Improvement in Input Current Distortion of Single-Phase Two-Stage Boost Rectifier
An improvement in the input current distortion of single-phase two-stage boost rectifier is studied. To cause the input current to follow its sinusoidal reference by means of current-mode control, a capacitor voltage is superimposed upon that of the supply when the switches are turned on. The experimental prototype, employing two insulated-gate bipolar transistors as active power switching devices and PI controller for output voltage regulation, is implemented to investigate the operation. The experimental results confirm that the input current can be waveshaped sinusoidally with a near-unity power factor independent of the working conditions.
