論文提要內容：本研究的目的主要將小型風力發電機系統，應用於電動車上，這是個非常具有環保及創意性的想法，不僅可以增加電動車的續航能力，且還能節能減碳減少石化能源消耗，由於電動車主要能量來自於鉛酸電池，在此本研究利用小型風力發電系統針對鉛酸電池進行充電測試。 本系統設計之微控制器使用單晶片PIC18F4520為控制核心，透過軟體的規劃控制，並搭配DC-DC降壓式轉換器電路，實現最大功率追蹤之目標。 本論文所設計之控制系統具備小型風力發電機組的過載保護功能，研製了一套具有保護發電機組的電路，以不致於在發電機高轉速或輸出電流超過額定的狀況下減少發電機壽命或損毀。 The propose of this research is use the Small Wind Turbine System(SWTS) applied in electric vechicles, which is a very environmentally-friendly and creative idea. Not only can increase the endurance capacity, but also can conserve energy to reduce carbon emission and the consumption of the fossil energy. Due to the main energy of the electric vehicles are from the lead-acid batteries, so we use the Small Wind Turbine System for charging test the lead-acid batteries in this research. The design of the system is use the single-chip micro controller PIC18F4520 as the control core. Through the planning-controlling of the software and with the DC-DC buck-converter to achieve the goals of the maximum power point tracking(MPPT). In this thesis, the design of the control system with overload and over speed protections for the SWTS,developed a set of generator protective circuit.It can avoid reducing the generator life or damages when the generator is in high speed or the output current exceeds the rated current.
