Piezo ceramic actuator is used for various industrial products such as spray, dispenser, and valve control etc. Since the deflection of the piezo ceramic element depends on the applied voltage, it is required a power amplifier with high voltage supply for driving the piezo ceramic actuators. In this paper, we develop a simple H-bridge type power amplifier and a compact flyback type high voltage switching mode power supply for piezo ceramic actuators. It is easy to adjust the amount of energy input to piezo ceramic actuator by pulse-width-modulation with H-bridge type power amplifier. Key Words : Piezo ceramic element, Impedance analysis, Flyback type converter, H-bridge power amplifier, PWM . * Corresponding Author : Soo-Yeong Yi(suylee@seoultech.ac.kr)Tel: +82-11-760-2491 email: suylee@snut.ac.kr 12 08 20 12 10 22 21 11 08 1. . , , . , .
