| Abstract: | For the current problem about the electrical matching in large power piezoelectric transducer,a comprehensive matching networking based on the advantages of series and parallel method is designed. In this case,output voltage and current could be superposition effectively,and the current quality is perfect as well. Phase difference and quality factor are considered as two important factors to measure the quality of electrical matching. |
