摘要

隨著科技產品的日新月異，穩定而有效率的電源需求也日益提高，而電源轉換器的並聯使用可以提供高可靠度及高功率輸出的電源供給需求，但並聯後的電源轉換器必須藉由均流技術來確保每個模組的輸出電流可以相同；因此本研究欲利用Arduino為控制核心，取代多個類比控制IC，以軟體方式實現平均電流之均流控制，研製多模組並聯DC-DC數位電源轉換器，確保每一部電源模組能平均地分擔負載電流，使各模組的輸出功率平均化，改善多模組供電的效率問題，並能穩定的供應電源。實驗結果顯示本研究所使用之並聯均流技術其均流誤差率均維持在±4%以內，效率達90%以上。另外，透過藍芽傳輸介面，利用Android環境開發工具App Inventor撰寫一遠端監控應用程式和Arduino建立通訊。使用者可從遠端線上調校控制器參數，節省控制器參數調校時間，並從遠端行動裝置即時監控系統資訊。

With the great advance of technology, the stable and efficient power requirements are highly demanded. The power converters used in parallel can provide the power supply with high reliability and high power output. The paralleled power converters must ensure that the output current of each module is with the same current according to current sharing technology. Therefore, this study intends to use Arduino as a control core to replace multiple analog control IC and implement the current sharing controller by software. The developed multi-module parallel DC-DC digital power converter ensures each power module can evenly share the load current, then improve the efficiency of multi-module power supply. The experimental results show that the error rate of the paralleled current sharing technology in this study can maintain in 5% and the efficiency can achieve 90% or more. In addition, by Bluetooth interface, we use App Inventor based on Arduino environmental development tools to write a remote monitoring program. Then we can make the connection between a mobile device and Arduino via a wireless way. Users can adjust the controller parameters from remote online to save the tuning time of the controller, and monitor the system information by mobile devices from remote area in real time.
