Hybrid power sources, including a fuel cell (FC), battery, and solar, are used in the proposed UAV power system to prolong the flight endurance time. For those multiple sources, the proposed integrated DC-DC converter involves in different functional structures, which offer performance optimization of FC and solar panel, charging/discharging operation of the battery, DC bus voltage regulation, and is able to perform in the regenerative operating mode if it is needed. A permanent magnet BLDC motor is employed for the system working with the multi-functional integrated converter. Moreover, the proposed integrated converter can also be used to charge the battery through the grid from any outlet charging station.

This paper uses the equivalent consumption minimization strategy (ECMS) method as the backbone of a novel approach named regen-based equivalent consumption minimization strategy (R-ECMS). The optimization-based algorithm accounts for the charge provided by the regenerative braking when computing the equivalent fuel cost. Although based on the ECMS, the R-ECMS does not share many of the usual limitations, such as having its performance constrained to drive cycles it is optimized for, and the necessity of having extra control rules for charge depletion situations. The results show that the R-ECMS method is more flexible and able to deliver charge sustaining and fuel efficient performances, which is key for plug-in hybrids. Besides, its fuel efficiency for the optimized case has shown to be slightly higher than the fuel efficiency achieved by the ECMS algorithm for the same optimized mission. Nonetheless, research on brake profile prediction must be conducted to allow leveraging the benefits of the R-ECMS algorithm in real applications.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130996850","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}

This work furthers the development of ferrite-less wireless charging pads by comparing an active and two distinct passive cancellation coil topologies as candidates to replace the ferrite. Using the software packages FEMM and MATLAB, each topology is optimized to find the best winding positions and radii to minimize leakage at a specified position under the side of the vehicle. The optimized designs are compared for shielding effectiveness, induced current, and efficiency. All three topologies are able to sufficiently reduce the leakage field below the ICNIRP limit of $27 mumathrm{T}_{text{rms}}$ with just one turn. Interestingly, we find that an array of simple passive cancellation loops performs similar to the more widely studied passive cancellation coil.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127224084","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}

Since the propellers are the primary power consumers in the AES, these fluctuations may significantly affect its power system power quality. Thus, for optimal performance of the ship power system, these fluctuations need to be rigorously investigated at the design level of vessels. Waves collision is one of the critical conditions where propellers inject power fluctuations into the ship power system. Therefore, a comprehensive model is essential to analyze the propellers in-and-out-of-water effect on the ship power system thoroughly at the design level. This paper proposes a model-based approach for determining propeller immersion depth variations in collisions with different wave classes. According to this approach, the propellers thrust loss factor caused by the in-and-out-of-water effect can be identified. The proposed method is then applied in an integrated AES model. This model interconnects the ship motion and power system dynamics. The in-and-out-of-water impact on the ship power system can be explored precisely in the model-based design of the vessels by utilizing the proposed model. In the end, the proposed method and the interconnected model have been used to simulate a notional ship in a wave collision condition. Simulations demonstrate that the proposed approach can accurately map the substantial impacts of the vessel-wave encountering conditions on the frequency, voltage, and generally on the power quality of the AES power system.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127360750","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}

Due to the unique requirements of the railway system, most of the EV coupler designs are not directly compatible with wireless charging applications for a train. To fill this technical gap, this paper discusses the design considerations for railway application and introduces a design of a modular 5-kW IPT system for rail locomotives. According to the design constraints, a novel W-I coupler is proposed for the 5-kW IPT system and the system is optimized via ANSYS Maxwell. A prototype of the proposed IPT system is developed at an airgap of 5 inches and 85 kHz operating frequency. The prototype has been validated in a 1.7 kW output power supply with a DC to DC efficiency of 85.6%. The experimental results validate the feasibility of the IPT system design for rail application.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127537535","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}

An appropriate selection of voltage is required to optimize cabling systems and distribute power onboard. The selection of the EPS's voltage is a compromise between weight and power transfer capability constrained by partial discharge phenomena at high altitudes and the aircraft's space availability. Hence, it is necessary to investigate the optimal voltage at which electrical power can be delivered such that cabling's weight and power transfer are optimised while the safety margins to avoid risk of physical discharge phenomena are observed regardless of the amount of power transferred. This paper addresses the selection of EPS optimal voltage for a direct current DC system and it will be shown that an optimized cabling systems does not necessarily require the highest possible voltage or the thickest conductor.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123704791","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}
