Conversion of the PWM output signal (differential and common-mode voltage components) of motor drives into a smooth sine wave with low residual ripple.Elimination of premature motor damage caused by high dv/dt, overvoltages, motor overheating, eddy current losses or bearing damage.Elimination of interference propagation towards components or conductors in the vicinity.Allows the use of extremely long unshielded motor cables without causing radiation problems (EN 55014, MDS clamp).Allows the use of lower rated drives with long motor cables due to lower losses in the IGBTs and in the motor cable
