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: increased switch consumption, higher
temperature increase, reduced output capacity;
under high carrier frequency, the inverter 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 inverter 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 1kHz carrier frequency.
