水下遙測系統電力電源之分析

Analysis of Power Supply Sources for an Underwater Telemetry System

本文對鉛酸電池與高分子鋰電池進行放電實驗，以觀察電池電壓與電流的變化，並了解電池也容量的續航力，作為選取水下遙測系統電力源之參考，另外，本文亦結合低成本之類比IC與降壓型轉換器，研製符合水下遙測系統內部設備如水下數據聲傳器，水下遙測單版電腦與垂直陣列麥克風訊號放大器等所需之電源規格，並測試轉換器於輕載切換至重載時，是否會影響轉換器之輸出電壓，以驗證轉換器設計的穩定性輿可行性。 Discharge experiments of lead-acid and li-polymer batteries are performed and the change of battery voltages and currents as well as the battery duration are observed in order to find a proper type of battery used for the proposed underwater telemetry system in this paper. Additionally, a low-cost integrated circuit (IC) and buck-type converters are used to obtain the power requirements for the facilities of the proposed underwater telemetry systems including underwater acoustic modems, a single board computer and vertical line array hydrophones with conditioning amplifiers. To verify the stability and feasibility of the designed power converters, the output voltages of power converters are measured as the load changes from a light load to a heavy load.
