本論文旨在探討如何使用多片壓電蜂鳴片作為能量轉換元件,並利用商用CAD軟體—Pro/ENGINEER來設計小型氣體渦輪壓電發電器,以進行發電能量擷取。
本論文所設計的壓電片發電機構分為三個部分:動力機構、傳動機構及發電模組,其中動力機構是利用高壓空氣驅動葉片轉動,傳動機構是利用凸輪及從動件之往復運動撞擊壓電片產生電力,而發電模組則是以多片壓電蜂鳴片串聯或並聯進行電能收集,此外再將回收的電能進行功率及效能的測試,驗證高頻發電的特性。
本論文所開發的壓電發電器經實驗量測的結果,其效能如下:當渦輪機轉速2635 rpm時,機械頻率為131.75 Hz,六片壓電片經整流後,外加負載電阻100 kΩ時,串聯及並聯瞬間最大功率可達139.2 mW,此能源可順利點亮LED。
The use of a piezoelectric buzzer as a component to generate electricity is discussed in this thesis. Commercial CAD software, Pro/ENGINEER, was used in the design of a mini air turbine piezoelectric generator to collect the generated electricity.
The structure for the piezoelectric power generator in this thesis consisted of three compartments: a power unit, a transmission system and a generator module. The power unit used a pneumatic driver to rotate a blade. Power was generated by the reciprocating motion of a cam and the follower as they struck the piezoelectric buzzers. The generator module collected electricity when the piezoelectric buzzers were connected in series or in parallel. Power tests were performed on the generated electricity to verify the system’s capability of power generation under high frequency of impacts on the piezoelectric buzzers.
Based on experimental results, the piezoelectric power generator developed in this thesis demonstrated the following: with the speed of the turbine at 2,635 RPM, the mechanical frequency set to 131.75 Hz after rectification, and six piezoelectric buzzers arranged in series or in parallel, the generator output power of 139.2 mW with a load resistance of 100 kΩ. The generated power was sufficient to illuminate a light emitting diode (LED).
