However, there still a problem to restrict further development of EVs is that how to efficient and fast charging for them. So, a kind of owns high-output-power and high-efficiency charging module may be a useful key to solve the problem. However, the conventional charging modules with using Silicon (Si) devices couldn’t own high efficiency, because there are a lot of power losses caused by power semiconductors and magnetic devices. Hence, reducing the amount of power semiconductors and magnetic devices to decrease power loss is a useful way to realize high efficiency. Therefore, according to the idea, this paper plans to design and implement a 15kWDC/DC converter charging for EVs with LLC resonant topology and Silicon-Carbide (SiC) devices to realize high efficiency, the proposed converter could reach to about 98.4% which calculated at rated full-load condition.

Conventional linear controllers have trouble obtaining the ideal control quality of simultaneously satisfying the performance requirements with respect to stability, speed, accuracy, robustness, and simplicity. This paper combines a proportional integral (PI) control rule with an adaptive parameter-adjusting circuit composed of memristors and adaptively adjusts the controller parameters through a memristor circuit to adapt to changes in system operation. The parameter update rules of voltage- and current-controlled memristors are discussed. The analysis indicates that under the control of the memristor-based adaptive PI controller, the closed-loop system’s output deviation continuously decreases along the gradient and approaches a minimum. Simulations and experimental verification are performed using a boost converter as the controlled object. The results show that, compared with a conventional PI controller, the proposed controller is more robust, and it is suitable for controlling a power electronic system with nonlinearly time-varying uncertainty and disturbance.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128890229","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}

Additionally, the voltage modulation ratio m can be promoted by utilizing the negative arm voltage output so that the power transmission and efficiency can be enhanced. However, under over-modulation operation $(m gt 1)$, the current and thermal distribution in HBSM and FBSM become different from that of traditional modulation $(m lt 1)$ due to the more complex modulation mode and operation principle. In this paper, the thermal distribution under different modulation index m and different power factor operation is emphasized in research. Under a high modulation ratio and a high power factor, the thermal unbalance among the devices of SM becomes more critical. In term of this issue, symmetrical modulation based active thermal control, which utilizes FBSM's redundant switch status, is proposed. With the proposed thermal control method, the thermal distribution among FBSM' devices becomes more balanced and the thermal stress of the power device with the highest temperature is reduced significantly. In the end, the theoretical analyses are verified based on a laboratory MMC prototype.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115641749","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}

Hence, it is not suitable for high-power Electrical Vehicle fast charging application. In order to overcome the above drawbacks, the double-inductor rectifier with separated resonant networks is introduced into the Phase-Shifted Full-Bridge, where the high-frequency transformer combining double primary windings with common secondary winding is adopted for the input-series output-parallel system connection. The proposed topology has achieved a wide range of the leading leg zero-voltage switching and lagging leg zero-current switching. The capacitors in each resonant network helps to reset the primary currents during the circulating period leading to more efficiency. Especially the switching losses and conduction losses of the diodes in each resonant network is lower, which has good performance in high-power conversion. According to the experimental result, the maximum efficiency is 98.5%. The operating principle, theoretical analysis, design considerations are verified on a 20 kW, 20 kHZ experimental prototype.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116401691","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}
