Abstract :
With its new SineFormertrade EPCOS is introducing a fully new output filter technology for frequency converters. In contrast to conventional filter topologies the new SineFormertrade simultaneously converts the phase-to-phase voltage into a sinusoidal signal, damps the common mode currents and also forms the conductor-to-ground voltage to sine shaped voltage. This offers users a number of key benefits. Voltage peaks are harmful for the motor windings are suppressed and bearing currents are reduced to negligible levels, thus significantly increasing the operating life time of the motors. The most important benefit is the cost savings. Because SineFormertrade practically eliminates EMC problems. Motors protected by the new filter do not require expensive shielded motor cables or special cable ducts.
