In this paper, the component stresses and the design optimization of a novel two-stage three-phase bidirectional buck-boost current DC-link PFC rectifier system, realized solely with SiC power MOSFETs and conveniently requiring only a single magnetic component, are introduced. This topology offers a high efficiency in a wide operating range thanks to the synergetic operation of its two stages, the three-phase buck-type current source rectifier stage and the subsequent three-level boost-type DC/DC-stage, which makes it suitable for on-board as well as off-board charger applications. The calculated voltage and current component stresses of the proposed converter system, considering an output voltage range of 200 to 1000V and up to 10kW of output power, help to identify its operating boundaries, maximizing the utilization of the power semiconductors and of the DC-link inductor. The optimum values of the circuit parameters are selected after evaluating the converter average efficiency $bar eta $ and volumetric power density ρ in the Pareto performance space and analyzing its design space diversity, focusing on the semiconductor losses and on the characteristics of the inductor. Considering typical EV battery charging profiles, i.e. taking both full-load and part-load operation into account, a power converter realization featuring $bar eta = 98.5% $ and ρ =13.9kW/dm3 is achieved.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128347390","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 topology comprises of reconfigurable primary power loops enabled by additional state switches. This combination allows the converter to run in parallel or series modes, enhancing the performance at both 230Vac high line and 115Vac low line mains. It reduces the voltage rating of devices, supports two operating points that operate in boundary conduction mode under fixed frequency and improves the utilization of the devices. A 75W, 90Vac-265Vac to 24Vdc converter has been designed and tested. The converter is compatible with efficiency enhancement solutions such as synchronous rectifier and quasi-resonant control presented in this paper. The experimental results show that the proposed converter has a significant performance improvement at universal mains without any additional efficiency enhancer and considerable performance improvement when using synchronous rectifier compared to a conventional Flyback converter. However, solutions that reduce high voltage stress are less beneficial to the suggested topology.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"21 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128537550","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}

However, the SC bank in hybrid ESS (HESS) deficits in delivering power for a longer duration to serve a higher number of transients. To reduce the burden on batteries and the overall system cost, a new auxiliary bank switching strategy for SCs with enhanced power delivery duration is introduced in this paper. A simple power management control is proposed to effectively switch the SCs from parallel to series combinations while serving the dynamic load demands. The key performance of the proposed circuit is holistically evaluated using PLECS simulations and a scaled-down laboratory prototype in terms of maximum power delivery time and SC cell energy utilization. The impact on passive components of the bi-directional converter with proposed architecture in terms of current stress is analyzed in detail. Finally, the suitability of the proposed architecture in HESS for an electric vehicle (EV) is verified on an OPAL-RT real-time simulator under a standard new European driving cycle.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129316091","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}
