DC reactor and Mains chokes relieves the supply network by compensating the harmonics reactive power. REO dv/dt chokes and filters attenuate due to their structure the voltage rise to acceptable values. Motor chokes reduce symmetric and asymmetric flow distortions , which are generated at the connecting line between the inverter and the motor due to the fast switching of the power semiconductors. Sinus filters guarantee sinusoidal output voltage for your frequency converter. The buck converter choke as an inductive passive component in the power supply and in power electronics is used to attenuate unwanted frequencies or for saving energy and storage.
