本文目標為設計並研製可重組式半橋 CLLC 諧振交流轉換器，架構中包含多組半橋 CLLC 諧振式轉換器與低頻主動全橋展開器，分別進行交流轉直流轉換、直流轉直流轉換及直流轉交流轉換。半橋 CLLC 諧振轉換器利用頻率調變控制輸出電壓，由於低頻主動全橋展開器是依市電相位切換，可大幅降低開關切換損耗。本文提出轉換器優點具有控制簡單以及可以應用在各種不同的電壓需求。本文採用三組半橋 CLLC 諧振轉換器並利用串聯或並聯連接的方式進行電腦模擬及硬體實作驗證架構之可行性，先以串並連接的模式實作 1.5kW 轉換器，測試輸入交流電壓為 380 Vrms，輸出交流電壓為 110 Vrms，最高效率約為 94.9%；再以串串連接的模式實作 1.5kW 轉換器，測試輸入交流電壓為 260 Vrms，輸出交流電壓為 220 Vrms，最高效率約為 94.5%；再以並串連接的模式實作 900W 轉換器，測試輸入交流電壓為 110 Vrms，輸出交流電壓為 220 Vrms，最高效率約為 93.5%；最後以並並連接的模式實作 1.5kW 轉換器，測試輸入交流電壓為 170 Vrms，輸出交流電壓為 110 Vrms，最高效率約為 93.1%。

The object of this thesis is to propose a reconfigurable half-bridge CLLC resonant AC-AC converter. The proposed converter is composed of multiple half-bridge CLLC resonant converters and bidirectional dc-ac unfolders. Because the unfolder only switches at the zero crossing of the ac line voltage, there is only one stage of high-frequency pulse frequency modulation (PFM), which is used to control the half-bridge CLLC resonant converter to generate the desired output voltage with galvanic isolation. The advantages of the converter proposed in this paper are control simplicity and connection flexibility for various applications. For the primary side and secondary side, the combinations of the connections include serial-parallel, serial-serial, parallel-parallel, and serial-parallel modes. Finally, computer simulation and hardware implementation are realized to verify the feasibility of the proposed converter. For the series-parallel connection, the rated power of the converter is 1.5 kW. The input voltage is 380 Vrms, and the output voltage is 110 Vrms with a maximum efficiency of 94.9 %. For the series-series connection, the rated power of the converter is 1.5 kW. The input voltage is 260 Vrms, and the output voltage is 220 Vrms with a maximum efficiency of 94.5 %. For the parallel-series connection, the rated power of the converter is 900 W. The input voltage is 110 Vrms, and the output voltage is 220 Vrms with a maximum efficiency of 93.5 %. For the parallel-parallel connection, the rated power of the converter is 1.5 kW. The input voltage is 170 Vrms, and the output voltage is 110 Vrms with a maximum efficiency of 93.1 %.
