C0018 fchop
6 Switching frequency of the
inverter
l General rule: The lower the
switching frequency the
– lower the power loss
– higher the noise generation
– better the concentricity
factor
l Observe derating indications
for high switching frequencies
l The max. output frequency
(f

) is:
– fchop = 4 kHz Þ
f
max
= 300 Hz
– fchop = 2 kHz Þ
