The signal integrity performance of printed circuit board links is influenced by a large number of design choices. Bayesian Optimization is a method that can optimize a large number of parameters in a reasonable amount of time. In this work it is shown that Bayesian Optimization can be used for the optimization of interconnect models with respect to their transmission and crosstalk performance. The first example is the optimization of the transmission of a single via. The second example is a 10 by 10 via array where the optimization includes transmission and crosstalk. The results obtained with the Bayesian Optimization are compared with the results of a Genetic Algorithm and with design guidelines derived from a physical perspective.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131585862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a novel semi-analytical approach to the computation of the self-interaction integral over rectangular domains is proposed for the zero thickness case as it occurs in the case of the coefficients of potential and partial inductances of very thin conductors and in the surface integral equation based formulation.

Nevertheless the real vehicle environment differs from the test setup. This results in a deviation of the component behavior during testing and in the target vehicle. To avoid redesign in late development stages the disturbance behavior of components must be characterized early on. A characterization can be obtained by modeling the component as a Thevenin equivalent disturbance source. A key aspect of this approach is the determination of the internal impedance of the component in active mode.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131204573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This implementation implies the so-called null-field approach. Both measured and simulated results for the transfer impedance of prototype models of the HV connectors are presented and compared for various numbers and shapes of apertures.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133705287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a well stirred RC, it is assumed there are sufficient number of plane waves, so the summation of the fields follows the well-known statistical distributions. Some researchers assumed a constant magnitude for the plane waves, while others assume a random distribution. Obviously the constant magnitude assumption is not physical in an actual cavity, as it would violate the conservation of energy. As a result, the model cannot simulate the Power Delay Profiles (PDP) in an actual RC. It was shown that the random distribution for the plane wave magnitude also produces unsatisfactory PDPs, and cannot match results from a Geometric Optics (GO) model. In addition, these models do not lend themselves well to simulate losses in a chamber. In this study, we propose a more physical model which is congruent with the behaviors predicted by the GO model. Monte Carlo simulation using the proposed model is then checked against the well-established statistical model in a RC.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"9 20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133266836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The three-phase HF motor model is acquired from CM and differential mode (DM) equivalent circuits, which are extracted from CM and DM measurements of the motor.

Magnetic couplings between the input/output paths and the shunt path are utilized to reduce parasitic inductance of the shunt path. To clarify effectiveness of the BMC in actual use conditions, filters are implemented to an IC Power Supply Line on a PCB under operating conditions.
