Due to the disturbances from the environment, e.g., winds caused by door opening and closing, sunshine, etc., a control system is needed for brain temperature. Biothermal models of the human body are usually very high, and is not suitable for the control of brain temperature. In this study, we construct a reduced-order biothermal model of the human body for the purpose of brain hypothermia based on the frequency characteristics of human thermal sensation. It features high precision in the frequency band for the therapy of brain hypothermia, and is suitable for the control of brain temperature.","PeriodicalId":377110,"journal":{"name":"2015 IEEE 24th International Symposium on Industrial Electronics (ISIE)","volume":"71 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128006850","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 conventional bidirectional converter was derived with auxiliary resonant cell to obtain ZCS turn-on/turn-off condition of the main switches. The proposed converter was operated in boost and buck modes with soft-switching operations in order to minimize the current stresses and switching losses, because the resonating current for the zero current switching does not flow through the main switches. The converter has an improved overall efficiency than the hard-switching converter, for high power energy storage applications.

Dynamic models provide accurate estimation of UC charge/discharge responses to varied inputs. Dynamic models are useful in predicting the behavior of UCs under varied load conditions. Also, it is critical to build an accurate UC model, which can be used for tests in various power electronics/drive simulation toolboxes. This paper aims at constructing an accurate dynamic UC model, which can estimate the output voltage without the extraction of the model parameters. The critical parameters have been determined dynamically from characteristic equations. The complete dynamic model is fabricated and simulation responses to charging and discharging pulses have been presented. Finally, the results obtained from the dynamic model are compared with the output voltage estimation results obtained from the popular equivalent RC-branch model.","PeriodicalId":377110,"journal":{"name":"2015 IEEE 24th International Symposium on Industrial Electronics (ISIE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131207864","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}

Accelerated aging tests have been carried out on 4 cells to address the effect of cold temperatures on Lithium-ion (Li-ion) batteries. Three of them were aged through a normalized driving cycle at three temperature tests (-20°C, 0°C and 25°C). The calendar test was carried out on one single battery at -20°C and mid-range of SOC (50%). Their capacities were continuously measured every two or three days. From the analysis, this paper shows that it is mandatory to consider the impact of cold temperatures on a battery pack lifespan. Therefore, there is a need for having a proper thermal strategy in order to keep the battery cell in the most appropriate operating condition and thus reduce the cold effect on the battery performances.","PeriodicalId":377110,"journal":{"name":"2015 IEEE 24th International Symposium on Industrial Electronics (ISIE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132883808","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}

Furthermore, the use of SRC provides a reduction of the low frequency (LF) ripple in the LEDs' current, originated by the voltage ripple in the output of the power factor correction (PFC) stage (bus voltage ripple). Thus, the attenuation of the ripple transmission from the bus voltage to the LEDs' current achieve some desired features: (1) reduction of the bulk capacitance used at the output of the PFC stage, enabling the employment of long-life film capacitors, and (2) increasing the efficiency of the LED driver due to the low switching losses of the series-resonant converter. This work proposes an analysis of the SRC aiming to define a design methodology to improve the LEDs current ripple reduction provided by the SRC. Moreover, the work presents a discussion about the main factors that have influence in the ripple reduction and the limits for this attenuation, which has not been explored in the literature yet. Experimental results employing the SRC to supply a 10 Watts LED lamp are presented, validating the feasibility of the employed methodology and the proposed analysis.","PeriodicalId":377110,"journal":{"name":"2015 IEEE 24th International Symposium on Industrial Electronics (ISIE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133365763","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}

Entitled as smart bicycle, this vehicles battery is being planned to be charged through energy harvesting solutions when in use or parked outside docking stations, or through an high power source when at the docking stations or during transportation. In these last two situations, the charging process may rely on contactless instead of galvanic contact charging, however, the non-invasive magnetic connection improves electric and mechanic reliability. Nowadays, there are wireless power transfer low cost solutions available for mobile devices, high cost solutions for electric vehicles like buses and cars, and there is a gap in the middle for solutions to apply in bicycles for example. In this paper, we propose a low cost contactless power transfer scheme based on a modification of a flyback configuration, that is described and circuit simulated. It uses a minimal number of components and thus, permits contactless battery charging with extreme simplicity and good efficiency.","PeriodicalId":377110,"journal":{"name":"2015 IEEE 24th International Symposium on Industrial Electronics (ISIE)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115802472","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}

Battery thermal models are required to avoid possible safety issues (thermal runaways, high-temperature gradients) but also for the optimal battery pack design and for predicting battery electrical performance during operation (especially at low temperatures). Equivalent electrical circuit battery models (thermal and electro-thermal) are able to offer relatively good performance with relatively low computational efforts and may be executed on-line (e.g. in the electric vehicle Battery Management System). The Electrothermal Impedance Spectroscopy (ETIS) can be used as a relatively simple and fast method for non-destructive parametrization of the battery thermal models. However, the ETIS requires expensive galvanostat with high-bandwidth and high-current capability for large format battery cells. Thus, this paper evaluates the possibility and accuracy of performing ETIS measurements with a standard battery test station (or bidirectional power supply) with low-bandwidth.","PeriodicalId":377110,"journal":{"name":"2015 IEEE 24th International Symposium on Industrial Electronics (ISIE)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114789993","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}
