本論文目的在於研究和設計一個高功率及高效率之直流電源供應器。電路前級採用兩相交錯式功率因數修正器，提高功率因數及降低輸入電流漣波。後級採用全橋串聯諧振轉換器，實現零電壓及零電流切換，減少開關元件應力，提高輸出效率，並具備輸出與輸入之間的電氣隔離。最後對實際設計的6kW電源供應器進行量測與分析，實驗結果證實，在輸入AC 380V的情況下，二級串接的整機滿載效率可達94%。

This thesis presents the study and design of a high-power and high-efficiency DC power supply. The front stage is a two-phase interleaved power factor correction (PFC) circuit to achieve high power factor and low input current ripple. The post stage is a full-bridge series resonant converter (FB-SRC) with zero-voltage switching (ZVS) and zero-current switching (ZCS). It can reduce the stress on the power switches, raise the efficiency and achieve electrical isolation between input and output. Finally, a 6-kW power supply is implemented and tested. The experimental results are shown to verify the feasibility of the proposed power supply. A 94% full-load efficiency is achieved by the cascaded two-stage circuit under AC 380V input voltage condition.
