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 inverter
temperature and the impact to the output capacity.
The inverter needs to derate on high carrier
frequency. At the same time, the leakage and
electrical magnetic interference will 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 reasonal carrier
frequency when the inverter is in factory. In general,
users do not need to change the parameter.
When the frequency used exceeds the default carrier
frequency, the inverter needs to derate 20% for each
