Abstract

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.

압전 세라믹 액추에이터는 스프레이, 디스펜서, 밸브제어와 같은 다양한 산업제품들에 응용된다. 압전 세라믹 소자의 기계적인 변위의 크기는 인가 전압의 크기에 의해 정해지므로, 압전 세라믹 액추에이터 구동을 위해서는 고전압 전원장치와 함께 전력증폭기가 필요하다. 본 논문에서는 간단하고 크기가 작은 H-브리지 형태의 전력증폭기와 플라이백 고전압 스위칭 모드 전원장치를 개발하였다. H-브리지 형태의 전력증폭기는 펄스폭 변조를 이용하여 압전 세라믹 액추에이터에 대한 에너지 입력의 크기를 쉽게 조절할 수 있다는 장점이 있다.
