摘要

本研究探討應用Zeta型升降壓電源轉換器設計太陽能飛機之太陽能/鋰電池混和供電系統。此系統使用DSPIC微控制器透過光敏電阻控制升降壓電源轉換器之輸出電壓與電流來達到鋰電池充電之控制與最大功率追蹤功能。光敏電阻之控制與最大功率追蹤之運算法則以模糊邏輯來執行。我們首先在MATLAB/SIMULINK環境上利用SIMSCAPE工具做電路模擬，成功完成模擬後，我們並設計及製作Zeta型升降壓轉換器與以DSPIC為核心之控制器。最後利用本設計成功的執行鋰電池充電與太陽能飛機之太陽能最大功率追蹤系統。

This thesis investigates the design of a Zeta type buck-boost converter based solar power and Li-ion battery hybrid power system for a solar-powered UAV. The output voltage and current of the power converter and the maximum power point tracking (MPPT) function are achieved through the control of a light dependent resistor (LDR) using DSPIC microcontroller. Control of LDR and MPPT function are implemented using fuzzy logic. Circuit simulation using SIMSCAPE tool on MATLAB/SIMULINK environment is established first. After that, a Zeta type buck-boost converter and a DISPIC microcontroller based control board are built. The battery-charging and MPPT functions using the self-designed system are successfully demonstrated on an experimental solar-powered UAV.
