摘　　要：阐述换能器的等效模型和超声电源应用中的动态和静态匹配方式。针对传统动态匹配中仅依赖相位判断的不足,提出了电流与相位结合的复合动态匹配方式。通过实验验证,该逻辑方案能够有效应对不同参数的换能器,以及因长时间工作导致的换能器频率漂移问题。This paper describes the equivalent model of the transducer and the dynamic and static matching methods in the application of ultrasonic power supply.It proposes a composite dynamic matching method that combines current and phase,targeting the traditional dynamic matching that only relies on phase judgment.Through experimental verification,this logic scheme can handle transducers with different parameters,as well as the frequency drift problem caused by long-term operation of transducers.
