5.3 Power loss
5.3.1 Power loss as function of switching frequency
If the operator wants to raise the switching frequency of the drive for some reason (typically e.g. in
order to reduce the motor noise), this inevitably affects the power losses and cooling requirements
according to the graphs below.
