Study on Hi-Power Precision Driving Power of Giant Magnetostrictive Actuator Based on Power Amplifiers

摘要：

　　According to the driving characteristics of giant magnetostrictive material and the principle of constant current source analysis,the continuously adjustable driving power was developed by adopting the principle of constant current,selecting power operational amplifier,and using parallel flow technology to expand its output current,which had a large current,large output power,high efficiency and low power consumption.And through the actual test,the driving power of giant magnetostictive actuator reveals a good performance.
