压电换能器驱动电路的设计
资料介绍
压电换能器驱动电路的设计,是整个测量系统的设计难点,国内通常采用的驱动电路,工作效率低、测量精度不能满足设计要求。文章通过对一款大功率压电换能器的设计实践,独创性地设计出一种单端激励的压电换能器驱动电路,利用脉冲变压器进行阻抗匹配和电压调谐,具有电路形式简单、易于操作的特点,同时创新性地利用电压谐振的设计方法,提高了压电换能器的工作效率。通过工业现场应用,产品性能指标达到设计要求。
The design of the driving circuit of a piezoelectric transducer is the difficulty for the measurement system. The driving circuits presently adopted in China have low efficiency and measurement accuracy. In this study, a single pole driving circuit for a high - power piezoelectric transducer was developed. A pulse transformer is used to fulfill the impedance matching and voltage resonance. With simple form and easy operation, the driving circuit has high efficiency.
