The purpose of the promotion work is to achieve an analysis of the parasitic couplings betwen surface-mount inductive and capacitative components in frequency range of 150 kHz-100MHz, depending from the components position, using 3D electromagnetic field simulation software. The promotion work consists of an introduction, three chapters and conclusions. The first chapter of work contain measurement metheology of the the surface-mount inductive and capacitative components parameters and the mathematical base of the measurement error analysis. The second chapter of work contain an analysis of parasitic couplings between surface-mount inductive and capacitative components using the 3-D electromagnetic field modelling tool and its error analysis. Several 3-D models for surface-mount inductive and capacitative components have been developed. The 3-D models are optimized to reduce the requirements of time and computational resources for analysis of parasitic couplings bettwen surface-mount components with 3D electromagnetic field simulation software. Knowledge acquired in this charpter can be used to reduced a parasitic couplings bettwen surface-mount components what can effect a EMI filter attenuation performance, using the 3D electromagnetic field modelling software CST MWS. The third chapter of work contain the optimisation and development of filter prototype BT, using knowledge wich acquired at work and 3D electromagnetic field modelling software CST MWS. The filter are designed to measure full resistance of loaded surface-mount inductive components in frequency range of 150 kHz-100 MHz. The prototype is compared with a filter equivalent on the market. The developed filter shows better parameters comparing with equivalent of the market available filter. Therefore, the 3D models for surface-mount components demonstrate effectiveness in filter development and optimisation the process with 3D electromagnetic field modelling software. The promotion work is written in Latvian. Work volume – 172 pages, 146 images, 15 tables and 52 sources of information, 2 attachments.
