用于超声振动切削加工的放大电路

The Amplifying Circuit Used in the Process of the Ultrasonic Vibration Cutting

本文介绍一个用于超声振动切削的新型ＡＣ－ＡＣ放大电路。该电路将输入０～５Ｖ正弦信号放大到０～４００Ｖ，并且在２０～５０ｋＨｚ的频率范围内输入信号的频率和电压可按需要进行调整，输出信号稳定。

The paper introduces a new kind of AC AC amplifying circuit for ultrasonic vibration cutting. This kind of circuit makes an input sine signal of 0￣5V being amplified to the value of 0￣400V, thereto, the input voltage as well as its signal frequency ranging from 20￣50kHz can be regulated according to the requirement, with the output signal being stable.
