Three-phase AC induction motors are designed to operate on three separate electric currents, which provide smoother, more efficient power delivery than single-phase motors.

EMIS announces the availability of the TMF4233 Three Phase EMI Filter with Neutral designed to be used in systems where noise ...

To understand common-mode noise, you need insight into how VFDs imitate a three-phase AC waveform. First, the frequency of the mimicked waveform is not what develops the noise.
