Abstract

Piezoelectric ceramic actuators utilize an inverse piezoelectric effect to generate high-frequency vibration energy and are widely used in ultrasonic energy conversion circuits. This paper presents a novel drive circuit with input-current shaping (ICS) and soft-switching features which consists of a front AC-DC full-wave bridge rectifier and a rear DC-AC circuit combining a stacked boost converter and a half-bridge resonant inverter for driving a piezoelectric ceramic actuator. To enable ICS functionality in the proposed drive circuit, the inductor of the stacked boost converter sub-circuit is designed to operate in boundary-conduction mode (BCM). In order to allow the two power switches in the proposed drive circuit to achieve zero-voltage switching (ZVS) characteristics, the resonant circuit of the half-bridge resonant inverter sub-circuit is designed as an inductive load. In this paper, a prototype drive circuit for providing piezoelectric ceramic actuators was successfully implemented. Experimental results tested at 110 V input utility voltage show that high power factor (PF > 0.97), low input current total harmonic distortion (THD < 16%), and ZVS characteristics of the power switch were achieved in the prototype drive circuit.

摘要

压电陶瓷致动器利用逆压电效应来产生高频振动能量，并且广泛应用于超声能量转换电路中。本文提出了一种具有输入电流整形（ICS）和软开关特性的新型驱动电路，该电路由一个前端AC-DC全波桥式整流器和一个后端DC-AC电路组成，后端DC-AC电路结合了一个堆叠式升压转换器和一个半桥谐振逆变器，用于驱动压电陶瓷致动器。为了在所提出的驱动电路中实现ICS功能，将堆叠式升压转换器子电路的电感设计为在边界传导模式（BCM）下运行。为了使所提出的驱动电路中的两个功率开关实现零电压开关（ZVS）特性，将半桥谐振逆变器子电路的谐振电路设计为感性负载。本文成功实现了一种用于驱动压电陶瓷致动器的原型驱动电路。在110V输入市电电压下进行测试的实验结果表明，该原型驱动电路实现了高功率因数（PF>0.97）、低输入电流总谐波失真（THD<16%）以及功率开关的ZVS特性。
