摘要

本文目的是設計一功率因數修正器及相移式全橋轉換器的串並聯式系統，前級功率因數修正器的輸入端採用串聯式連接，且功率因數修正器採用平均電流控制法，後級相移全橋轉換器輸出端採用並聯式連接，其中相移全橋轉換器則利用信號之相移，調變工作週期，使轉換器的功率開關元件工作在零電壓切換，進而減少於功率開關元件上的切換損失。
本文使用德州儀器公司所生產之數位信號處理器 TMS320F28035作為控制平台， 驗證實作及設計的正確性；本文所研製的系統規格包含輸入電壓220 V/60 Hz、輸出電壓 12 V、最大功率為 600 W、功率因數修正器切換頻率為80 kHz及相移全橋轉換器切換頻率為80 kHz。
實驗結果證明此串並聯架構電路可以正常運作且穩壓，由以上結果驗證設計與實驗的正確性。

The objective of this thesis is to design and implement a series and parallel system of power factor corrector and phase-shift full-bridge converter. The inputs of power factor correctors are connected in series and the PFC is controlled using average current mode control. The outputs of phase-shift full bridge converters are connected in parallel and phase-shift control is applied to the full-bridge converter control to achieve ZVS and thereby reducing the switching loss of power devices
A digital signal processor, TMS320F28035, TI, is used as the controller for the realization. The specifications of the system are as follows:
Input voltage = AC 220V
Output voltage = DC 12V
Output power = 600W
Switching frequency of power factor corrector = 80 kHz
Switching frequency of phase-shift full-bridge converter = 80 kHz

Experimental results show the design specifications can be met and thereby confirming the effectiveness of the topology.
