Abstract
In this article, a transfer function-based modelling is proposed to investigate voltage oscillation phenomena, i.e. over-voltage at the motor terminal, associated with pulse-width modulation (PWM) inverter-fed motor drives with long feeding cables. As such, the long feeding cable is assumed to be a distortionless transmission line; then, a bounce diagram and time-harmonic method are utilised to derive a simple model with a minimum computational burden that is easy to realise using the Matlab/Simulink software package. Furthermore, the model takes account of the inverter output and the motor terminal filters, which are commonly used to suppress the motor terminal over-voltage. The model accuracy is verified by a comparison with the circuit-oriented software, OrCAD/PSpice, simulation results.
