摘要: | 本論文探討的目標,為在各種力電耦合係數下之多整流壓電陣列與單整流混合陣列之優劣比較。比較方向是其功率表現、頻寬拓寬與二極體損耗,比較方法為透過理想係數之假設,製造出不同力電耦合下的環境,再利用單整流混合陣列之理論推導與多整流壓電陣列之理論推導,進行理論分析與其模擬。結果顯示,在強力電耦合係數的環境下,不管是在功率表現或二極體損耗,單整流混合陣列會有更優異於多整流混合陣列之表現。最後進行強力電耦合係數下之兩系統實驗,來驗證先前之預測的正確性。 The goal of this thesis is to carry out the performance evaluation of an array of piezoelectric oscillators based on multiple rectifiers for respective electrical rectification and a single rectifier for overall electrical rectification. Such comparisons are evaluated based on various electromechanical couplings for output power, bandwidth and electric diode loss. The methodology is based on the theoretical analysis and SPICE numerical simulations under the condition of virtual system parameters for producing different electromechanical couplings. From the point of view of output power and diode loss, the simulations show the mixed array with overall electrical rectification outperforms the array with respective electrical rectification. Finally, these predictions are validated by experiment. |
