Abstract :
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.
