In order to protect drives, cables and motors from the overvoltage caused by reflections the obvious solution is to reduce the bus voltage [1] with respect to the cable insulation rating. Even with 100% overshoot in voltage, an IGBT drive with 300Vdc bus…

Standing waves in PWM motor drives and their effect on the actuator control.
The inverter of the PWM drives does not produce sinusoidal output voltage waveforms; instead, it generates a continuous train of pulses which are transmitted to the motor terminals via the motor cable. Peak pulse voltage atthe drive outputis equalto the…
