This paper describes the techniques used to analyze and to simulate problems associated with Adjustable Speed Drives (ASD). Overvoltage mitigation techniques are evaluated. The complete system, including power cables and induction motor is simulated using the ATP version of the Electromagnetic Transient Program (EMTP). A new method to reduce overvoltage in the cable due to switching of the IGBT is proposed. Comparisons between the new method and others traditional methods likes filtering are included.
