本論文研製一操作於連續導通模式之圖騰柱功率因數修正器，其輸出功率為600W、輸入電壓為交流110V、50Hz/60Hz、開關切換頻率100kHz、輸出電壓則為介於380V至430V之線上可調式電壓。本文針對圖騰柱功率因數修正器的動作原理與硬體架構設計進行詳細分析與探討並且加以實現。在控制方面採取數位控制，相較於傳統類比控制其主要優點為控制靈活性高。本文採用德州儀器公司所推出之TMS320F280049C做為本電路之控制核心，在研製電路過程中本文運用韌體實現零交越緩啟動控制法以改善輸入電流在零交越點產生之電流突波，並搭配調整正負半週之中斷觸發點與類比數位轉換器的取樣點，以及使用責任週期前饋技術降低輸入電流總諧波失真。最後由實驗結果得知，上述控制法可改善輕載至滿載之輸入電流總諧波失真與功率因數，且本電路之最佳輸入電流總諧波失真為2.27 %，當負載大於30%後功率因數皆可達0.99。

In this thesis, a totem-pole power factor corrector operating in continuous conduction mode is developed. The output power is 600W, the input voltage is AC 110V, 50Hz/60Hz, the switching frequency is 100kHz, and the adjustable output voltage is between 380V and 430V. In this thesis, the operating principle and hardware design of the totem-pole power factor corrector are firstly analyzed and discussed in detail and then implemented. In terms of control, digital control is adopted in this study. Compared with traditional analog control, its main advantage is high control flexibility. In this thesis, the TMS320F280049C introduced by Texas Instruments is used as the control core. This study uses the firmware to realize the zero-crossing soft-start control method to improve the current surge generated by the input current at the zero-crossing point. Combining the adjustment of interrupt trigger points of the positive and negative half cycle as well as the analog-to-digital converter sampling points with the usage of the duty cycle feedforward technique, the input current total harmonic distortion can be reduced. Finally, the experimental results show that the proposed control method can improve the input current total harmonic distortion and power factor from light load to full load, and the optimal input current total harmonic distortion of this circuit is 2.27 %. When the load is greater than 30%, the power factors are all above 0.99.
