摘要

本論文之目的主要為研製一可應用於不斷電系統中之昇壓轉換器與變頻器，首先藉由昇壓轉換器將48V直流壓提昇至400V，接著再以變頻器將此直流電壓轉換為110Vrms/60Hz之交流電壓。
為了節省電路、零件與設計成本，昇壓轉換器將不做穩壓控制，僅針對變頻器之輸出進行取樣與分析並完成閉迴路控制，最後再以TMS320 F2812數位信號處理器做為控制核心，完成全數位化控制。
本論文所研製之電路其詳細規格如下：
輸入電壓：DC 48V。
輸出電壓：AC 110Vrms/60Hz。
額定功率：600W。
切換頻率：昇壓轉換器為100kHz，變頻器則為12kHz。

The objective of this thesis is to design a fully digital-controlled boost converter and inverter for UPS applications, the converter boosts the DC 48V to DC 400V, and the inverter converts the DC 400V into AC 110Vrms/60Hz.
To save circuit components and cost, the output of the boost converter is not to controlled. The output of the inverter is regulated by sening it’s voltage and controlled by TMS320 F2812 DSP.
The specifications are as follows:
Input voltage：DC 48V
Output voltage：AC 110Vrms/60Hz
Output power：600W
Switching frequency：100kHz for boost converter, and 12kHz for inverter.
