60 min


An increasing trend in the industry is to combine power and control cables into a single hybrid cable design, reducing the complexity of the system and cost. However, without careful design, high voltage power switching transients may lead to unwanted electromagnetic interference. Typical hybrid cable design parameters may include the separation between conductors, twist rate of twisted pairs, shielding and screen types. This webcast will explore the simulation of hybrid cable design using CST® CABLE STUDIO and the prediction of EMI levels. Topics covered will include the modeling of shield transfer impedance, crosstalk and induced common mode currents.
