A new approach to analyze the overvoltages due to the cable lengths and EMI on adjustable speed drive motors


This paper presents a new model allowing the evaluation of the over voltages caused by the length of the cables feeding motors driven by PWM-controlled VSI. This model is elaborated using the mobile-wave theory. A full mathematical analysis of the voltage at the motor terminals is developed taking into account inverter output voltage rise and fall times and… (More)
