论文摘要
本文研究了控制电动机驱动器电动机阻抗的可能性。现有的解决方案（或消除）由SI-IGBT或基于SIC-MOSFET运行的电动机的反射波影响是使用正弦波滤波器或DV/DT滤波器。本文中建议的替代解决方案是在电缆末端或电机端子上实现高带宽电子电路，以匹配电缆和电机的涌现阻抗。由于电缆参数和电缆的长度，由于电动驱动器中反射的波形而引起的高频电压响声约为1 MHz。在提出的方法中，电子电路可以快速检测DV/DT上升边缘，并在脉冲到达电动机端子时调节电子电路等效阻抗。因此，可以在短时间内匹配电缆和电动机阻抗，以防止反射波。结果，可以显着抑制穿过球轴承的泄漏电流和电动机绝缘上的过电压。
This article studies the possibility of controlling the surge impedance of the electric motor in motor drives. The existing solution to suppress (or eliminate) the reflected wave impact on the motor insulation run by a Si-IGBT or SiC-MOSFET-based drive is to use either a sinewave filter or dv/dt filter. The alternative solution suggested in this article is to implement a high-bandwidth electronic circuit at the end of the cable or at the motor terminals to match the surge impedance of the cable and motor. The high-frequency voltage ringing due to the reflected waves in motor drives is around 1 MHz, depending on the cable parameters and the length of the cable. In the proposed method, the electronic circuit can quickly detect the dv/dt rise and fall edges and adjust the electronic circuit equivalent impedance when pulses arrive the motor terminals. Thus, the cable and motor surge impedances can be matched over a short time to prevent reflected waves. As a result, the leakage currents passing through the ball bearing and overvoltage stress on the motor insulation can be suppressed significantly.
