| Abstract(in English) | This paper, the simplified inputcurrent shaping technique by using inductor voltage control for high power factor flyback rectifier is introduced. In the controller, the duty ratio is obtained by comparing a signal derived from the inductor voltage sensing of the power transformer with a negative (slope) ramp carrier waveform. The shape of the carrier waveform is determined from the relation of the rectified inductor voltage and steady state DC conversion ratio of DC-DC flyback converter in CCM operation. Using this current shaping technique, input line voltage sensing, error amplifier in the current feedback loop, multiplier/divider in the voltage feedback loop and current transformer or current sensing are eliminated. To verify the ideal of the new technique, the experiment is applied to 100W flyback rectifier. As the results, the input current waveshape is closely sinusoidal, implying high power factor. |
