Transient Analysis of Motor Terminal Voltage, Common Mode Voltage and Bearing Voltage in 2-level and Multilevel PWM Inverter Fed Induction Motor with Long Cable

2023 International Conference on Distributed Computing and Electrical Circuits and Electronics (ICDCECE), 2023
The long motor cable contributes to overvoltage and higher common-mode voltage (Vcm) at the motor terminals fed by the PWM inverter due to the voltage reflection phenomenon. Higher the Vcm, higher the induced bearing voltage (Vb) and the bearing currents.
