The double degree master's program Electric Vehicles and Energy-Saving Technologies was chosen as an example. This program is being implemented within the framework of the Erasmus + CybPhys grant project between Kharkiv National Automobile and Highway University and Riga Technical University. The stages of launching a double degree program between partner universities are described on the example of the implementation of the Erasmus + CybPhys project. The algorithm of actions when starting the program into the educational process and the conditions for its implementation are indicated. The problems that arose during the launch of the double degree program are considered and the ways of their solution are described. An example of the development of the course “The structure of hybrid and electric vehicles”, which is part of this program, is presented. The implementation of the double degree program through grant projects opens up additional opportunities. One of these is the opportunity to purchase specific equipment necessary for the educational process. This article is intended to help representatives of educational institutions that have no experience, but plan to launch double degree programs in the future, in the implementation of similar projects.","PeriodicalId":194535,"journal":{"name":"2021 IEEE 62nd International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117170024","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 research, we analyzed methods and tools of the quality monitoring system. One of the elements of the quality monitoring system is creation of the Project Quality Monitoring and Control Team (PQMC) that manages quality monitoring process in partner’ universities, which comprise the project consortium. The PQCM Team developed a comprehending reporting system, which is based on self-evaluation and peer review approaches. The universities Teams, which implement internal quality procedures, report on education programs accreditation at national and university levels, results from monitoring (peer review) visits to participating universities.

The aim of the project is to create a controllable luminaire to illuminate the surgical table. To improve the efficiency of the luminaire, it is built on the basis of LED. To ensure a change in the illumination spot, the luminaire changes its geometry, for the intensity it is dimmed by the driver. Mossy ICEs emit an enormous amount of heat, which must be removed from the room. In this work, the calculation of the heat removal system for the luminaire is shown.","PeriodicalId":194535,"journal":{"name":"2021 IEEE 62nd International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116255474","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 many converter topologies, a transformer with specific parasitic components could be needed. For example, in the phase-shifted full-bridge converter, bidirectional dual active bridge converter dc-dc converters, or LLC resonant converters, the leakage inductance of the transformer needs to be precise as it influences the overall performance of the converter. In this paper, a simple yet effective technique has been investigated to design high-frequency transformers with adjustable leakage inductance. The transformer is designed to be used in a 100 kHz series resonant dc-dc converter, where the leakage inductance of the transformer is used as the resonant inductor. The proposed design technique utilizes the variation of the winding structures where a split bobbin separates primary and secondary windings. At first, the finite element analysis (FEA) based simulation is performed to estimate and analyze the leakage inductance with different winding structures, and then the experimental investigations are performed. Both the simulation and experimental results demonstrate that by simply varying the winding arrangements in the hybrid split-bobbin transformer, the leakage inductance can be changed while keeping the magnetizing inductance of the transformer constant.","PeriodicalId":194535,"journal":{"name":"2021 IEEE 62nd International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"318 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131434349","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}
