Abstract

Modeling the electromagnetic emissions from a complex product such as a TV presents many challenges due to the complexity of electromagnetic interaction between multiple noise sources and interconnected resonant structures. A set of advanced methods such as the design and use of substitution boards for electromagnetic interference analysis, a practical simulation model for verifying the accuracy of the passive structures of the TV, an empirical scaling factor for incorporating the main processing board using the Huygens Equivalence theorem and modeling the radiation due to the flex cable based on active probe measurements is presented. The combined model comprised of the relevant noise sources and structures allowed the prediction of the most critical radiated emissions and the total radiated power caused due to the display signals.
