A New Driving Power for Dynamic Applicat ion of Piezoelectric Ceramics

The principle and limitations of existing driving powers for piezoelectric actuators are analyzed first, then a newly developed driving power is presented in detail. Experiments show that when input signals are dynamic,such as rectangle wave or square wave,its output can follow input very well. With its excellent dynamic performance,the new driving power can meet the needs of dynamic driving of piezoelectric elements.
