Abstract :
When supplying an induction motor by a PWM-inverter, reflection phenomena occur if the supply is done through long motor cables. Several papers discuss by simulations or experiments the overvoltage appearing at the motor terminals. The consequences of the overvoltage are a widespread topic. This paper deals with other reflection phenomena observed with different PWM-inverters. Stairstepping and the influence of the dead-time generator on the reflections are analysed.
