dU/dt filters for today’s drive and automation technology
TRAMAG products explained
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.
