The advantage of high carrier frequency: ideal
current waveform, little current harmonic wave
and motor noise.
The disadvantage of high carrier frequency:
increasing the switch loss, increasing VFD
temperature and the impact to the output
capacity. The VFD needs to derate on high
carrier frequency. At the same time, the leakage
and electrical
increase.
Applying low carrier frequency is contrary to the
above, too low carrier frequency will cause
unstable running, torque decreasing and surge.
The manufacturer has set a reasonable carrier
frequency when the VFD is in factory. In general,
users do not need to change the parameter.
When the frequency used exceeds the default
carrier frequency, the VFD needs to derate 10%
for each additional 1kHz carrier frequency.
Setting range:1.0–15.0kHz
0: Invalid
1: Valid during the whole process
The auto-adjusting function of the VFD can
cancel the impact on the output voltage of the
VFD because of the bus voltage fluctuation.
