FUSS du/dt-Filters are used to reduce the voltage slew rate at the output of frequency converters to values below 500 V/µs.
du/dt-filters are simple and cheap devices to optimise in a simple drive system. du/dt filters are damping the rate of change of approx. 10.000 V/sec down to a low rate . This results in a more smooth running drive system with less noise and increases the long life period of a motor.
