According to automotive standard CISPR 25, electronic components or modules are required be connected a specific test cable bundle in order evaluate the radiated emissions. In absorber-lined shielded enclosure (ALSE) method, also called antenna is often dominant radiation structure due its length. This measurement method requires large anechoic chamber, but often, it only impact of bundle's common-mode (CM) current distribution that measured. Since can measured easily with clamps, and much...
Based on the problem of electromagnetic interference in darkroom connected vehicle communication systems, a research method is proposed to evaluate wireless quality between antennas using gain coupling. The compatibility far-field radiation pattern, coupling degree, and near-field pattern antenna model were analyzed by establishing 3D simulation external transmitting antenna. obtained data, arrangement scheme can be determined. performance index automotive OTA then tested determined scheme,...
In automotive EMC ALSE method, specified in CISPR 25, is commonly used for emission measurements. Components or modules are required to be connected with a test cable bundle evaluating radiated emissions. The radiation often mainly dominated by the common mode current along bundle. order predict emissions from setups according without using large anechoic chamber, this paper presents an alternative and innovative method. presented approach determines fields phase information. It only based...

The radiated immunity of passenger cars and commercial vehicles is validated using electromagnetic interference from off-vehicle radiation sources in an anechoic chamber according to the procedure ISO 11451-2. Common electrical or electronic vehicle systems, including dual flash, monitors, entertainment must be a standardized evaluation procedure. However, Automated Driver Assistance System (ADAS) functions often lack verification complex fields, which might create potential risk due...
Abstract. Today EMC emissions of automotive components are often measured in anechoic chambers by an antenna at fixed position according to CISPR 25 (ALSE-method). The voltage cannot sufficiently describe the behaviour electronic and systems. Furthermore space requirements costs very high for ALSE-method. Field- cable-scan methods combined with near-field far-field transformation techniques might be a good alternative. Residual reflections from walls, metallic floor, measuring table,...
Due to the high-voltage and high-current operating characteristics of electric drive system vehicles, it forms strong electromagnetic interference during working process. The shielding effectiveness connection cable that connects components is directly related its emissions. Therefore, modeling analysis very important for development a with good effectiveness. Firstly, transfer impedance value representing shielded analyzed, difference between single-layer shield double-layer compared....

This paper investigates instrumentation effects that may limit the usefulness of pre-compliance bench-top test methods for e.g. CISPR 25 radiated field measurements. Here fields are dominated by common-mode currents along cable bundle especially when frequency is below several hundred MHz. From a known current distribution, can be computed. The measured using probes with measurement instruments like oscilloscopes or spectrum analyzers (SAs). However, because low limits, very small (amplitude...
