| 中文摘要 | TUUSAT-1爲總重約34.7公斤的微米級衛星,預計以搭便車的方式發射於高度500至800km的太陽同步圓軌道。本文將根據TUUSAT-1任務與軌道規格,訂定電源次系統的需求與電力預算,並依電力預算估算太陽能電池有效面積大小與蓄電池放電深度,作爲選擇太陽能電池與蓄電池的依據。電源次系統採用直接能量傳輸(Direct Energy Transfer, DET)架構,穩壓器採用切換式的DC/DC轉換器作爲3.3V、5.0V與12V的穩壓輸出,以提高轉換效率;鎳氫蓄電池的充電器控制使用馳返型電路,採用定電流充電方式,也裝設了電壓、電流和溫度感測裝置,可由星上電腦做電力控制與資料讀取。 |
| 英文摘要 | TUUSAT-1 is a microsatellite weighted about 34.7 kg and is expected to be launched by piggyback on a Sun-synchronous circular orbit with the altitude around 500 to 800 km. In this paper the requirements and power budget of the power subsystem will be determined according to the mission objectives and orbital specifications of TUUSAT-1. Then the architecture and circuit hardware will be designed according to the operational requirements of power subsystem. The effective area of solar cells and discharge depth of batteries will be evaluated according to the power budget for selecting the proper amounts of solar cells and batteries. The power subsystem adopts the direct energy transfer architecture and the power management and distribution unit. In order to increase the transfer efficiency, the constant voltage regulator adopts the switching DC/DC converter with the constant voltage output of 3.3V, 5.0V and 12V. The storage battery pack uses the Ni-H batteries and the battery charger adopts the flyback converter and is charged with a constant current. The voltage, current and thermal sensors are also installed for the house-keeping of spacecraft. The flight computer can control the hardware of TUUSAT-1 power subsystem presented in this paper and distribute the power to the onboard loads. |
