Radiated emissions modelling of a power cable

Abstract

This paper presents two numerical methods to compute quickly radiated emissions of a cable linking a power converter and a motor. 3D model is not built to be compliant with industrial process (short time development). The field is directly deduced (thanks to Matlab programs) from the common mode current and the load impedance. Simulations are compared to measurements on an inverter mock-up designed by Airbus France. Measurement set-up is performed according to DO160 standards. Modeling results show a good correlation with measurements.

Regulate drain‐shield relative positioning and contact for mitigating radiated emission from USB cables

“…Throughout the test, a movie file of around 12 GB is continuously transmitted from the phone to the PC. Both the devices are enclosed in metallic shielding, with no apertures or slots except for necessary interfaces; thus, they can be considered well-shielded devices, the overall RE of the phone-cable-PC system is dominated by the emissions from the cable alone [1,2,[18][19][20].…”

“…Introduction: Radiated emission (RE), a metric assessing electromagnetic noise emitted by information technology equipment (ITE) into the external environment, is predominantly influenced by emissions from attached cables in well-shielded ITE [1][2][3][4][5]. As communication speed and cable complexity continue to rise (e.g.…”

An extended EMC study of an electrical powertrain for transportation systems

“…Almost every manufacturer of transportation systems extends his portfolio of products with electric drives [1,2,3]. The simplified structure of the electrical powertrain (see Figure 1) can not only be influenced from outside, it can also emit disturbances.…”
