Most of the employed motors are permanent magnets (PM) based and these materials are subjected to price fluctuations. In addition, they are not the key for sustainability, especially when referring to rare earth materials. An alternative to the classic PM motors is the wound field synchronous machine (WFSM) which, thanks to the absence of magnets, represents an inherent more sustainable solution. In addition, this machine presents higher controllability and fault tolerance compared to their PM counterpart, which on the other hand features higher torque density and efficiency values. While WFSMs have been widely adopted and studied as power generators in grid-connected and isolated power plants, their use as traction motors is limited and under investigation. This paper aims to resume the state of the art of WFSMs and to analyze the challenges of its employability in the automotive field. Possible future developments, contextualized considering the authors' vision, will be also discussed.","PeriodicalId":38493,"journal":{"name":"AUS","volume":"4 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76365179","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 modern electric transportation systems (such as aircraft, road vehicles) can greatly profit from embedded FPGAs, which incorporate both high-performance and flexibility features into a single SoC. At the same time, the virtualization of FPGA resources aims to reinforce these systems with strong isolation, consolidation and security. In this context, we present a novel virtualization framework aimed for SoC-attached FPGA devices, in a Linux and Qemu/KVM setup. The solution uses Virtio as a means to enable the configuration of FPGA resources from guest systems in an efficient way. Also, it employs the Linux VFIO and Device Tree Overlays technologies in order to render the FPGA resources dynamically accessible to guest systems. The ability to dynamically configure and utilize the FPGA resources from a virtualization environment is described in details. The evaluation procedure of the solution is presented and the virtualization overhead is benchmarked to show that performance degradation is minimal (around 10%) when accessing the FPGA devices from guest systems.","PeriodicalId":38493,"journal":{"name":"AUS","volume":"37 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82113485","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}
