The prevalence of EMI noise problems has been considered many times over the past few years, in inverter fed motor control systems. The advent of high speed power devices, and the high dv/dt of switching devices, has resulted in EMI problems and leak

In this paper, filtering techniques to reduce the adverse effects of motor leads on high-frequency PWM inverter fed AC motor drives are examined. The filter was designed to keep the motor terminal from the cable surge impedance to reduce overvoltage
