Thus, this paper proposes a generalized simplified modeling method for the electromagnetic coupling effect on uncertainty strapping cable bundles. Firstly, the Gaussian distribution and spline interpolation are applied to determine the location of the core conductors in the random bundling. Then, the inductance matrix and capacitance matrix of the cable bundle at different position are established by using transposition relationship between the subsegments of the conductors. Finally, the effectiveness of the proposed method is verified by numerical simulation.","PeriodicalId":194675,"journal":{"name":"2020 6th Global Electromagnetic Compatibility Conference (GEMCCON)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122642919","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}

By the assistance of model, metric or optimization, FSL can not only make use of the prior information, but also gain the ability of learning the pattern for distinguishing and classifying input vectors from only a few samples. For transient electromagnetic disturbances, the recurrent neural network (RNN) is involved to help with the memory of the input signal with the style of 1-D time sequence. In order to learn the proper feature of transient disturbances, a Siamese neural network containing two RNNs is built and trained, and the distance of two outputs can be measured by a preselected distance function. This makes the proposed model capable to learn the difference between normal cases and failure cases. In order to demonstrate this method, a pulse current injection testing on a certain electronic system is conducted and evaluated with the metric-based FSL. The result confirms the practicability of the proposed model, for the correct classification rate can be 83.3% with only 36 samples.","PeriodicalId":194675,"journal":{"name":"2020 6th Global Electromagnetic Compatibility Conference (GEMCCON)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115199284","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 main difficulty of the broadband partial element equivalent circuit (PEEC) modeling for an inductor is the presence of magnetic materials. In this paper, this electromagnetic difficulty is solved by replacing the magnetized object with a fictitious magnetic current distribution in free space, which is determined according to the boundary conditions. Based on the PEEC method proposed, broadband models of a toroidal inductor and a printed circuit board (PCB) EI core plane inductor in switched mode power supply are established to predict their frequency-dependent impedance. This approach is verified with the results gotten using the finite-element method simulations and measurements. The three models show good agreement for impedance above 200MHz frequency.","PeriodicalId":194675,"journal":{"name":"2020 6th Global Electromagnetic Compatibility Conference (GEMCCON)","volume":"32 18","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113934499","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}
