Advantages of high carrier frequency are as follows:
ideal current waveform, few current harmonics and
small motor noise.
Disadvantages of high carrier frequency are as
follows: growing switch consumption, enlarged
temperature rise, impacted output capacity; under
high carrier frequency, the VFD needs to be derated
for use, meanwhile, the leakage current will
increase,
which increases electromagnetic
interference to the surroundings.
While low carrier frequency is the contrary. Low
carrier frequency will cause unstable operation at
