The successful SineFormerTM series of EMC output filters has been extended by a range designed for applications up to a rated voltage of 760 V. The new B84143V*R290 spectrum of filters is available in current stages of 95 A,180 A and 320 A. Depending on their type, they are operated at clock frequencies from 2.5 kHz. Versions for 600 A and 1000 A are in preparation. |

Never again shielded cables The SineFormer%u2122 from EPCOS is an output filter that is easy on the motor and makes shielded motor cables superfluous. It allows costs to be reduced while improving performance. Asynchronous motors must often be operated at continuously variable speeds. Pulse-width modulated frequency converters with an unregulated input rectifier shape the DC voltage from the DC link circuit to an output voltage by using suitable driving of the semiconductors (usually IGBTs) |
