However, in real case, factors such as parking misalignments, load variations and coils inclination would result in a deviation of coils mutual inductance, which may adversely impact on system transmitting efficiency. Therefore, an approximately real-time identification method of mutual inductance is proposed in this paper to help achieve the current maximum efficiency in a non-ideal system. Moreover, the Discrete Fourier Transform (DFT) algorithm is used to reduce sensor noise and eliminate harmonics. Simulation and experiment results verify the accuracy of the method of mutual inductance identification.","PeriodicalId":242505,"journal":{"name":"2017 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115494251","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, due to complicate magnetic coupling relationships between the coils it is difficult to analyze and design these system. Regarding to this problem, a metal-insulator based magnetic decoupling method is proposed in this paper, so that the complicated multi-coil WPT system can be decoupled into several independent two-coil sub-systems. In this way, the output characteristics for each subsystem can be designed independently, and passive compensated network is applied to guaranteeing constant-voltage output. The transmission efficiency and the constant-voltage effectiveness for a four-coil WPT system are analyzed in theory, and some simulation and experimental results are given as well.","PeriodicalId":242505,"journal":{"name":"2017 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126276114","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}

Then, not only is the receiver more compact, but also the stability of WPT system is further ensured. Based on the simulation and experimental results, it show that when the load varies, CV charging for SS compensation and CC charging for SP compensation are achieved by the PI controlled phase shift H-bridge inverter.

In consideration of low coupling coefficient caused by long transmission distance, a relatively high current level should be kept when using the traditional serial-serial topology(referred to as S-S topology), which increases the system energy loss and rise the breakdown risk on switching devices. The CCL topology could provide a relatively high equivalent impedance and still keeps the current on transfer coil high enough. The characteristic of this topology and the analysis of system efficiency at different load are given.

Recently, the DD type has been proposed as the EV's charging magnetic coupler design, which already has been shown to have the best performance in the stationary charging. For dynamic wireless charging, the output power fluctuates when EV moves. This paper seeks to optimize the magnetic coupler to realize all the dynamic WPT system's demands. A crossed DD coil design is proposed to solve the \"almost zero mutual inductance phenomenon\" when EV moves from one primary coil to the next one in this paper. Besides, LCC resonant network is employed in both primary and secondary sides to ensure the constant current, and even to make a better output performance.
