The carrier frequency can be reduced when it
came like following phenomenon:
1 The leakage current generated by the
inverter is large
2 The interference generated by the inverter
has an impact on peripheral devices
3 Long wiring distance between inverter and
motor
The carrier frequency can be increased
whenwhen it came like following
phenomenon:
1 The electromagnetic noise generated by the
motor is large

PWM way
0
:
SVPWM
It is normally used
1
:
SVPWM+DPWM
Using this modulation method can reduce the
switching loss of the inverter and reduce the
probability of overheating alarm of the
inverter; however, the electromagnetic noise
of the motor in the medium speed section will
be too large.
2
:
PWM at random
The electromagnetic noise generated by the
motor is white noise, not a sharp squeak.
