通过在压电驱动器收缩时回收其在伸展时储存于其电场和应变场中的能量，来提高对驱动压电驱动器动作的激励电源使用效率。
By recovering the energy that has stored in the electric field and strain field when some piezoelectric actuator extends during its contracting , we can improve the efficiency of the stimulant power supply which is used to drive the piezoelectric actuator .
