Abstract in another language
This paper presents a closed-loop control approach to mitigate overvoltage at the motor by introducing an intermediate voltage level. The key contribution lies in using measurements taken from the converter side with minimal additional components, thereby eliminating the need for direct voltage sensing at the motor terminals. The proposed method utilizes the detection of the cable oscillation amplitude to optimize the timing of intermediate voltage steps, effectively reducing motor-side overvoltage. The approach is validated through an experimental setup, where a simple algorithm demonstrates its ability to determine the optimum timing under stable operating conditions. However, for scenarios involving rapidly changing operating points, a more advanced algorithm that accounts for current dynamics and semiconductor switching behavior may be necessary.
