摘要
压电换能器长时间、大功率工作时 ,其各种电参数会随环境因素 ,特别是自身温度变化而改变 ,这种变化直接影响电声转换效率。本研究在分析压电超声换能器电感电容匹配电路原理的基础上 ,按照各项性能参数改变对电端匹配电路的影响规律 。
Based on the research of inductance capacitance matching circuits for piezoelectricity transducer,the matching affection made by the change of transducer parameters is analyzed.A new electricity matching circuit that has more adaptable capability for a demanding invariable frequency is proposed.
