![]() All filter components used in the model construction are available in the integrated Filter Components Library.īelow are presented models for film capacitor (WCAP-FTX2 MKP Film Capacitor 890324023025) and toroidal choke (WE-CMB S 744 822 301) with calculated S-data: In this application note we constructed 3D models of the filter components, calculated their S-parameters with fullwave MoM solver and used them in circuit simulation. For 3D MoM fullwave simulations filter components should be modeled as voluminous objects with corresponding frequency-dependent material parameters. ![]() ![]() In circuit simulations, filter components can be defined either as circuit elements with nominal values and stray parameters included in the circuit element definition or based on measured/simulated S-parameters. Modeling of the WE Components for Fullwave and Circuit Simulationsįilter components used for assembling of filter model can be modeled in EMCoS Studio environment in different ways depending on the chosen simulation method (circuit or 3D MoM fullwave analysis). The filter samples and corresponding simulation models were constructed using passive components and evaluation board from Würth Elektronik EMC-Filter Design Kit 744 998. The EMCoS Studio software package supports all required tools to perform accurate modelling of filter components and fast assembling of filter models. ![]() Depending on initial data availability, either circuit simulation approach, or 3D fullwave simulation can be applied. It shows different techniques for modeling of EMC filter performance assembled based on Würth Elektronik EMC-Filter Design Kit in EMCoS Studio environment. This application note demonstrates the results of cooperation project between EMCoS Ltd. ![]()
