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 raise, 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
low frequency, decrease the torque, or even lead
to oscillation.
The carrier frequency of VFD is set properly by
default, and it should not be changed by users at
will.
If the default carrier frequency is exceeded during
use, derating is required, derate by 10% for every
additional 1k carrier frequency.
