What is Voltage Reflection in PWM Inverters about?

The document discusses the impact of high-frequency switching in PWM inverters on induction motors, particularly focusing on the adverse effects of voltage rise rates and cable lengths on motor insulation and bearing currents. It explains how PWM pulses behave as traveling waves, leading to voltage reflections that can double the voltage at motor terminals, potentially causing insulation stress. The document also outlines methods to mitigate these over-voltages, including filtering techniques and enhancing
