    Abstract: 本論文主要設計可程式之非反向同步式升降壓直流-直流電源轉換器。整體架構分為直流-直流電源轉換器與微控制器兩部分。直流-直流電源轉換器負責執行升壓、降壓或是升降壓的動作,微控制器負責讀取數據,判斷該執行升壓、降壓或是升降壓後,控制直流-直流電源轉換器執行相對應之動作。
    此一系統架構在本論文中使用在太陽能電源系統的最大功率追蹤,藉由微控制器判斷功率點後,控制直流-直流電源轉換器執行升降壓,來達到最大功率點,以取得最佳效率提供給負載端所需電源,透過修改程式,此一架構也可以應用在電源穩壓器上或是鋰電池充放電管理系統。
    我們測試其轉換效率並利用太陽能模擬機進行最大功率追蹤測試,再直接以太陽光進行最大功率追蹤測試,確定其有辦法正確運作後,最後將其安置在UAV上進行飛行測試。
    This thesis presents the design of a programmable non-inverting synchronous buck-boost dc-dc power converter. The system contains two major subsystems, namely, a synchronous buck-boost power converter and a control unit. The buck-boost converter is capable of converting the source supply voltage to higher and lower voltages to the load terminal with voltage polarity unchanged. The voltage regulation is achieved through the control of a specially designed feedback circuit using a light dependent resistor from the control unit. A feedback control system to ensure the performance of the power converter is established. The hardware/software integrated and function tested prototype system is built in the laboratory. The system is successfully utilized for the maximum point tracking for the solar power management system using natural sunlight as the irradiance source. The system can be tailored to other power control applications through minor modification to the software of the control unit.
