摘要

本文的创新之处在于采用了基于传输线建模技术的四导体电缆束频域模型，而没有假设线路是无损的。包括数学模型的详细文档。实验室测量验证了该模型，该模型预测了由以下因素引起的电机端子电压峰值:1)不同的电机电缆尺寸和几何形状2)逆变器dv/dt的变化3)应用于电缆的电压步长变化4)插入电机端子以控制dv/dt的终端网络。

Application of the transmission line theory to the frequency domain analysis of the motor voltage stress caused by PWM inverters

The innovative contribution of this paper is the application of a frequency domain model based on the transmission line modeling techniques for a four conductor cable bundle without the assumption of lossless lines. A thorough documentation of the mathematical model is included. Laboratory measurements validate the model which predicts the peak motor terminal voltage caused by: 1) different motor cable sizes and geometry 2) variations of the inverter dv/dt 3) variations of the voltage step size applied to the cable 4) termination networks inserted at the motor terminals to control the dv/dt.
