目前超音波壓電共振之熱熔技術於工業上之應用已漸獲得重視，而開發壓電驅動更具有其實務應用參考價值，因此本文即設計換流器輸出高頻電壓，並藉由霍爾元件回授換流器電流，及經由回授電路判別後，利用場規劃邏輯閘晶片設計控制換流器之開關，以使換流器產生適當頻率之電壓，且經由適當頻率與電路設計之選擇，期使換流器開關於不同頻率下，皆可達到零電壓切換，俾以提升系統效能，降低開關溫度，並同時有效驅動壓電共振陶瓷產生機械振盪，以驅使系統穩定運作。本文同時推導換流器系統之輸出電壓與輸入電壓之關係，並經由模擬驗證本文所提之控制系統正確性，且實作雛型電路及紀錄實測波形，以佐證本文所提電路之可行性及實務採行之參考價值。

With an increased concern of ultrasonics piezoelectric transducer systems, the development of inverters to be suitable for such an industrial application system has gained a higher practical value nowadays. In this thesis, the resonant inverter circuit of high frequency that is controlled by field programmable gate array to drive ultrasonics piezoelectric systems has been completed with a high success. Meanwhile, the developed system owns the capability of zero-voltage switching(ZVS), hence exhibiting the merits of low power loss and temperature rise. To validate the effectiveness of the method, this thesis has investigated the voltage relationships between input and output as well as examined the corresponding waveforms. Test measurement help confirm the feasibility and practicality of the method for the application applied.
