The equivalent circuit model of a piezoelectric transformer is useful in designing and optimizing the related driving circuits. Based on previous work, an equivalent circuit model for a circular flexural-vibration-mode piezoelectric transformer with moderate thickness is proposed and validated by finite element analysis. The input impedance, voltage gain, and efficiency of the transformer are determined through computation. The basic behaviors of the transformer are shown by numerical results.
压电变压器的等效电路模型在设计和优化相关驱动电路方面很有用。基于先前的工作，提出了一种中等厚度的圆形弯曲振动模式压电变压器的等效电路模型，并通过有限元分析进行了验证。通过计算确定了变压器的输入阻抗、电压增益和效率。数值结果展示了变压器的基本特性。
