    • INSPIRESat-1 衛星搭載的科學酬載為小型電離層探測儀 (Compact Ionosphere Probe, CIP) ，其主要目的為量測電離層電漿參數，如離子密度、離子組成、離子速度、離子溫度與電子溫度。由於CIP必須安置於3U立方衛星裡面中，其內部空間有限，必須盡可能縮小探測器體積至1U以內。CIP內部主要由三張電路板所疊構而成，而本論文內容主要著重於第三張電路板的開發與研製，稱之為電源管理單元 (Power Management Unit, PMU) 。主要目的為將衛星提供的電源進行轉換並分配至探測器內部三張電路板的電子元件與模組上。由於PMU為探測器的電源核心，內部勢必要有保護機制去避免突波電流或是SEL (Single Event Latch-up) 而危害探測器系統的元件。電路設計是採用 NI Multisim 電路設計軟體與 NI Ultiboard 的電路佈局軟體。參考各項元件的規格書，設計並研製CIP所需要的PMU電路功能。最後透過CIP內部三張電路板的整合並放置於電漿環境中量測電漿資料，驗證其設計與功能的正確性。

    CIP (Compact Ionosphere Probe) is the only one science payloads on the INSPIRESat-1. The purpose for CIP is measuring ionophere parameters. Including the ion concentrations、ion velocity、ion temperature and electron temperature. The CIP is seted up in the 3U cubesat. Due to the space limit, it have to minimum the sensor volume into 1U space. In the CIP interior, it is assembled by the three PCBs. The thesis is focus on the development and design of the third PCB. The third PCB is called Power Management Unit (PMU) . The main purpose of the PMU is to let CIP normally operation by convertering the satellite power and distributing the power to the every components in the CIP. PMU also be integrated into the CIP, too. The PMU controls the power system of the CIP. It must have the protection device to avoid the components damage because of inrush current or SEL (Single Event Latch-up) . The circuit design is using the NI Multisim software and the layout is using the NI Ultiboard software. Refering the specification of every components, end then designing the circuit that is correspond to function requirement of the PMU. Finally, combinating the three PCBs and deploying in the plasma enviroment measure the plasma to verify the design and function normally.
