摘要

本篇論文是以場效可程式化閘陣列(field-programmable gate array, FPGA) 為核心之內嵌式系統, 搭配類比數位轉換器(A/D converter) ADC0809 建立主動感測控制器之感測技術來實現交流輸入電源之功率量測, 並搭配光耦合器(photo coupler) 和電晶體放大電路來控制負載輸入電源端的電磁接觸器(Magnetic Contactor) 的激磁線圈, 藉此來達成負載輸入電源的導通及斷開之控制。
數位控制實現是使用友晶科技研發之DE2-115開發板, 再選擇Verilog 邏輯程式來撰寫FPGA之關鍵性嵌入式邏輯軟體技術, 其FPGA晶片為Cyclone IV EP4CE115F29C7。控制演算法是在軟體環境Quartus II 中, 使用Verilog 硬體描述語言作程式設計。
在實作中, 我們將以一組單相交流電當輸入, 並以整流後之直流輸出於550W 之可變負載, 其中交流輸入電壓範圍為90~264V, 由實驗結果顯示: 在不同輸出負載情況下,其交流輸入電流絕對誤差約在0.2A 以內, 藉此證明主動感測控制器之程式演算法是可用的。

In this thesis, the embedded system of the field programmable gate array with a analog to digital converter (ADC0809) is used to establish an active sensing system to realize AC input power for power factor, current, and voltage paired with optical coupler and amplifier to control the load input power at the end of electro-magnetic contactor excitation coil so as to achieve load input power conduction and disconnection of the control.
We use DE2-115 embedded system with the chip Cyclone IV EP4CE115F29C7 and write Verilog logic programming for FPGA key logic embedded software. Control algorithm in the software environment is Quartus II and Verilog hardware description language program design.
From experimental results by using AC input ranging from 90V~264V and variable DC output loads within 550W, the AC input current absolute error is about 0.2A in different load cases, which shows that the effectiveness and availability of the proposed active sensing controller program algorithm.
