本論文主要目的係研製一具有高功因、低諧波、高效率及高功率密度之無橋交錯式連續導通模式功率因數修正器。雙相交錯式控制策略不只保有傳統單相脈波寬度調變無橋式轉換器的優點，且在高輸出功率下更可改善功率元件高耐流、儲能電感體積過大、輸出電容過大及EMI濾波器體積等問題。
本論文實際製作一3.4 kW無橋交錯式功率因數修正器，以驗證所提之分析與設計考量是否合理，實作電路之控制IC使用德州儀器公司所生產的20腳位UCC28070。經測量結果證明，雙相交錯式架構確實可以減少電流漣波，適用於大功率應用場合。整體電路於輕載到滿載能有效穩定輸出電壓，中載到滿載功率因數皆在0.96以上，在輕載至滿載實測效率皆可達96%以上，且在切換頻率75 kHz，輸入電壓為264 V，輸出3.4 kW時有最高效率為98.8%。

This thesis is focused on the design and implementation of a two-phase bridgeless interleaved (BILI) boost power factor corrector (PFC) under continuous conduction mode (CCM) to achieve a high power factor, low input current harmonics, high efficiency and high power density. A two-phase bridgeless interleaved boost PFC features the advantages of a single-phase PWM bridgeless converter. In addition, the current ratings of the power switches, and the volumes of the inductors, output capacitors and EMI filters can be reduced.
A 3.4-kW two-phase bridgeless interleaved boost PFC is implemented in the laboratory. Experiments are conducted and satisfactory results are measured to confirm the effectiveness and the feasibility of the theoretical analysis and design considerations. The UCC28070 is used as the control IC for the PFC. It is verified that the current ripples are greatly reduced with the two-phase interleaved topology. Thus the two-phase interleaved PFC are especially suitable for serving as a pre-regulator in the high-power applications. The DC output voltage is well-regulated. The power factor is greater than 0.96 from half load to full load. The measured efficiency is greater than 96% from light load to full load. A peak efficiency of 98.8% is recorded at 75-kHz switching frequency, 264-V input and 3.4-kW load.
