| Summary: | 碩士 === 國立海洋大學 === 電機工程學系 === 88 === A fixed frequency, fixed duty cycle boost converter with continuous input inductor current for power factor correction operation is introduced in this paper. Thus, the proposed topology has much lower input harmonics and much better EMI performance than the conventional boost converter. By using coupled inductor technique, the input inductor current ripple can be free, the high frequency harmonic distortion can be avoided, and the low frequency input current waveform distortion is analyzed. Simulation results are presented that the proposed boost topology has the advantages of lower switch voltage stress, lower switch current stress and lower voltage stress on the capacitor.
