摘要
介绍一种夹心式超声刀驱动电路。在实现自动频率追频功能的基础上,加入自动增益控制电路达到恒流驱动和功率自适应的功能,最大程度地保证换能器工作效率的要求。设计了自动增益控制电路和整个驱动电路,并通过实验进行了测试验证。
This paper introduces a sandwich ultrasonic tool drive circuit.On the basis of the automatic frequency tracking function,an automatic gain control circuit is added to achieve the functions of constant current drive and power adaptation,thereby ensuring the requirements of the working efficiency of the transducer.The automatic gain control circuit and the entire driving circuit are designed,and the circuit is verified through experimental tests.
