Switching of high frequency current, despite of application of soft switching techniques, causes serious stress to the switching device. The parasitic components of both driver and power circuit can further disrupt the commutation process and contribute to the significant FFT spectra deterioration. Thus, a resonant filtering circuit was proposed, which significantly reduced voltage oscillations and improved operation of 4 MHz RF generator. Significant improvement was proven for both 50 Ω load and mismatch conditions.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124874879","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 the testing phase of these devices and systems, position data is usually artificially produced and fed to the systems, so that systems can be tested based on variable positioning information. This approach enables the testing of many different cases/scenarios (using different position information) on the device/system in a short time and at a low cost. However, the position data feeders/generators used in these tests and the device are tested as a conjugate pair. The interoperability test of these devices/systems that have their own position generator cannot be made due to synchronization problems. In this study, a framework that generates positions is proposed to perform integrated testing of many interactive systems in a performant and realistic way. In the performance tests of this proposed and developed framework, low resource usage was observed. According to the test results, position data can be fed to more than 1000 clients in a new generation high-end system that will run this program alone.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121134723","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 two-dimensional Finite Element Method is one of the most relevant ones when the objective is performing modal analysis, and Mode-Matching is widely used when analysing discontinuities in terms of modes. Due to the synergies between both methods, it is very interesting to study their combination in special cases commonly appearing in the literature, such as the problem of discrete rotationally-symmetric waveguides. In this work we present how the integration of the 2D Finite Element Method for Mode-Matching with rotationally symmetric modes must be done, so that it may employed to perform a more efficient and accurate analysis of devices composed of waveguide discontinuities.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121326286","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 approach is based on reformulation of well-known equations representing filter scattering parameters S11 and S21 for a given coupling matrix. With the use of relation connecting inverse matrix its determinant and its adjugate matrix the system of equations is formed. The equations are reformulated in a way allowing direct comparison of polynomials coefficients for numerator and denominator of S11 and numerator of S21. This enables to form the system of polynomial equations, where unknowns are all entries of searched coupling matrix. In the proposed approach no conversion from S-parameters to Y-parameters is needed like in most of published techniques. SINGULAR software (GPL license) using Groebner basis for solution of such a system of polynomial equations was used. Two numerical experiments have been presented. First one CM synthesis for 4th order (one cross-coupling) filter. Second one is CM synthesis for 8th order (two cross-couplings) filter. Both experiments showed excellent results obtained with the proposed method. The method works for S-parameters of filters with arbitrary topologies.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132119003","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}
