摘要
介绍一种高压可调大功率动态驱动电源的设计,它用于高速微小孔振动钻床振动装置的压电陶瓷激振器,可以实现压电陶瓷的可控振动,其主要由D/A控制卡、放大电路、高压直流电源电路等几部分组成。该驱动电源具有线性好、容易控制等优点。
In this paper, a new dynamic driving power for vibrating drill press with piezoelectric actuator, which is composed of D/A card, magnified electrocircuit, and high voltage DC circuit. The dynamic driving power can excite the vibration of piezoelectric actuator, and it is easy to control and to keep linearity.
