针对压电换能器的串并联谐振频率附近难以确定其最优匹配阻抗参数等问题，采用saber软件对阻抗匹配过程中匹配电感的参数进行仿真分析，以研究匹配电感参数对串并联谐振频率区电流大小及高频变压器次级电流电压相位差的影响。同时，对空载、加载等工况下串并联谐振区进行实验研究与验证。研究结果表明：将匹配电感调至最佳值时，压电换能器的输出电流最大，高频变压器次级电流电压相位差为零；压电换能器在空载工况下，其工作于串联谐振状态时的性能较好；而在加载工况下，其工作于并联谐振状态时的性能较好。

For the difficult problems in determining the optimal parameters during matching impedance near the parallel resonant frequency of the piezoelectric transducer,the parameters of matching inductance were anylyzed imitatively during matching impedance using saber software. The effects of the inductance parameters matched on either large or small of the electric cuttent in the range of resonant series and parallel frequency and on the difference of phase between current and voltage in secondary of high frequency transformer were studied. And the experimental studies and verifications were carried on the range of series and parallel resonant frequency under conditions of no-load or load. The results show that the piezoelectric transducer output current is at its maximum,and secondary side current and voltage phase difference of high frequency transformer is zero,when the matching inductor was adjusted to a suitable size. Under condition of no load,piezoelectric transducer working with series resonant will has a better work performance. However,under condition of load,piezoelectric transducer works efficiently under parallel resonance zone.
