本論文提出設計並實現太陽能無人飛行載具之電源管理系統，以提供機載電腦系統 (OBC) 之電力使用。此電源管理系統主要分為三級 : 第一級為最大功率追蹤(MPPT)，其主要目地是用來收集太陽能，並且追蹤太陽能板隨著溫度與照度而改變的最大功率點，以得到最佳效率提供負載端之電源使用。第二級是電池管理 (BM)，鋰高分子聚合物電池為充/放電管理之蓄電池，共分為二個電池模組，其一用來做電力轉換之電壓源，另一則不斷攫取從太陽能板經最大功率追蹤後之電力，並用來當備份電池。第三級為電力轉換 (PC)，將電壓轉換為 +5V 與 ±12V 以提供系統及機載電腦之所需。 In this thesis, we designed and implemented a power management system for a solar powered UAV. The power management system will provide the power required for the on-board computers on UAV. The power management system mainly consists of three stages, the maximum power point tracking, the battery management, and the power conversion stages. The first stage (MPPT) attempts to obtain the maximum power available from the PV panels. The second stage, battery management, controls the charge and discharge processes of the Li-Ion polymer battery modules. The third stage is for power conversion which converts input voltage to +5V and ±12V for the OBCs and all other electronic circuitries.
