The analysis was performed before and after long-term delicate modification by argon ions by X-ray photoelectron spectroscopy using numerical simulation of the interaction of ion beams with the target surface in the SRIM software package. At different durations of low-current ion sputtering of niobium oxide, the formation of metastable stoichiometric and non-stoichiometric nanosuboxide layers of various thicknesses, as well as their sputtering, was found. The study shows that it is possible to create the necessary nanosuboxide layers, the structure of which is determined by the performance of functional devices.","PeriodicalId":272476,"journal":{"name":"2021 3rd International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127929936","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}

Existing Ethernet networks can be used to synchronize devices. However, the devices have to support special protocols at the hardware level. A time synchronization algorithm based on the Precision Time Protocol (PTP, IEEE 1588-2008) is considered, which can be used in any data transmission network with a deterministic delay in the transmission line. The use of this protocol in synchronous Ethernet networks allows achieving subnanosecond accuracy of time synchronization between the devices. Hardware and software implementation as well as the results of measuring the synchronization accuracy with multiple system restarts and phase noise measurement are presented.","PeriodicalId":272476,"journal":{"name":"2021 3rd International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134453227","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}

Linear PMSM design was developed. Its magnetic field was simulated to obtain the PMSM starting characteristic. The optimization task of the highest power efficiency was solved in this work. The experimental PMSM sample was manufactured and researched. The simulated and experimental forces amounts have a significant difference. Probably it is caused by the scattering fluxes. Thus, it is recommended to design the winding divided into coils. In this case, some coils can be switched off during the PMSM operation. It reduces scattering fluxes and increases power efficiency. Besides, the research results showed that the magnets’ form and magnetization significantly affect PMSM power efficiency. The most important result of this study is understanding the possibility of PMSM usage for piston compressors driving.","PeriodicalId":272476,"journal":{"name":"2021 3rd International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132072088","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}
