dU/dt filters for today’s drive and automation technology

TRAMAG products explained

dU/dt filters belong to the group of output filters, as they are used directly at the inverter output, upstream of the connected drive units – developed precisely to fit the individual drives system.

Due to increasingly efficient, fast-switching power semiconductors in the inverters, motor windings are additionally loaded. With a high-quality dU/dt filter from TRAMAG, these interference pulses and voltage peaks generated by the inverters are significantely dampened.

This is achieved by the low-pass effect of the LC combination (choke plus capacitors) of the dU/dt filter, designed above the clock frequency of the inverter.

Downstream motors are thus subjected to a reduced voltage load, which has a positive effect on the service life and availability of the motor operation.

TRAMAG has been an experienced manufacturer of filters and other winding goods for almost 100 years and convinces customers from a wide range of industries with its technical expertise.
