| 摘 要： | 针对弹光调制器需要高压、小电流双向正弦电源的工作特点,设计了一种压电晶体驱动控制器,主要由功率放大电路、充放电回路、LC谐振电路等部分组成。它能提供正负输出,并能对压电晶体进行快速充放电。输出正弦电压频率为50.018 kHz,峰-峰值电压可达1 500 V,ZnSe晶体的最大振动位移可以达到4.5μm。实验结果表明,该驱动控制器可满足压电晶体的驱动要求。

| Abstract: | As to the characteristic of photoelastic modulator need the bidirectional high voltage and low current,a driving power for piezoelectric crystal is developed.The driving power is composed of the charging and discharging circuit,LC resonant circuit.It offers the bidirectional voltage and discharges it rapidly.The maximal sinusoidal output voltage can reach up to 1 500 V (peak to peak),and the output frequency is 50.018 kHz.The biggest vibration displacement of ZnSe crystal can attain to 4.5 μm.The experimental results show that the driving power can meet the requirement of the piezoelectric crystal. |
