摘要

本論文主要研製一功率放大器測試設備(Laboratory Power Amplifier)所需之電源，其架構包含一具功因修正的昇壓型轉換器與提供多組輸出給功率放大器及其周邊正常工作之返馳式轉換器。藉由邊界電流模式控制器L6561來控制前級昇壓型轉換電路；同時藉由電流模式控制器UC3845控制後級返馳式轉換電路。最後，藉由理論推導、模擬及硬體實作以驗證所提架構之可行性。

The purpose of the thesis focuses on developing the power supply to feed the laboratory power amplifier. Such a power supply contains one boost converter with power factor correction (PFC), one multi-output flyback converter with two output voltages feeding the power amplifier and with additional two output voltages feeding the peripheral circuit of this power supply. Regarding the control methods used herein, the boost converter is controlled by L6561 whereas the flyback converter is controlled by UC3845. In this paper, the mathematical derivation is firstly introduced, and secondly some simulated and experimental results are provided to demonstrate the effectiveness of the proposed topology.
