Experimental Research of Electrical Output Characteristics of Stacked PZT-5H Under High-Overload Conditions

摘要

Stacked piezoelectric ceramics (PZT-5H) are often used as sensors and pulsed power sources in moving objects. They will be subjected to a larger overload force when the moving objects collide with the target. In order to study the influence of the connection mode (parallel/series) of ceramic chips on the electrical output characteristics of stacked PZT-5H during overload, many experiments were performed using a nylon projectile to impact the stacked piezoelectric ceramic with different impact velocities by using a one-stage light gas gun as the loading device. The influence of a full bridge rectifier circuit on electrical output characteristics of the stacked PZT-5H was analyzed.
