【摘要】 为了解决直流放大式压电陶瓷驱动电源在实际应用中存在输出电压纹波较大且幅值随输出电压大小而改变的问题，对其工作原理进行了深入分析，在此基础上提出了采用恒流源代替其放大级电路负载的方法。实验表明，这种方法有效地抑制了电源的纹波及其变化。更多还原

【Abstract】 In order to solve the problem of big ripple voltage of the DC amplifying mode electric circuit of power supplied for piezoelectric actuators, deep analysis of the principle of power has been made in this paper On the basis of this, a method is put forward to replace load of amplifying circuit of the power supplied for piezoelectric actuators with constant current source The experiment results show that the ripple voltage and its variation of the power could be restrained effectively更多还原
