Relationship bet ween Model and Carrier frequency

This f unc tionis m ainly used t oimprove the m otor operating noi seand i nvert er int erfe rence to external.

The a dvantagesof using high carrier frequency: re latively ideal current w ave shape, less harmonic

current waveand low motor nois e;

The situat ionsof usingl owcarrier frequency is on the contrary. Too low carrier frequency canc ause
