초록
In this paper, ultrasonic nozzle and driving circuit were manufactured, respectively. And then, their electrical properties. were investigated. Ultrasonic nozzle was fabricated using PSN-PMN-PZT ceramics showing excellent piezoelectric characteristics. In order to drive ultrasonic nozzle, PWM controller(KA3525A) was used. The purpose of this study is to find the optimal driving condition of ultrasonic. nozzle. Accordingly electrical and temperature characteristic of ultrasonic driving system were investigated as a function of the input voltage.
