However, it has not been discussed conventionally the optimum coil type, material, and construction method embedded in the road. Therefore, in this study, we evaluated the electrical characteristics by embedded seven DWPT coils in the road and compared the coil types, coil case materials, and construction methods. As a result, we clarified the changes in the characteristics of the open-end coils before and after embedment. There are two types of coil, short-end coil (conventional) and open-end coil that does not use resonance capacitors. There are four types of coil case materials: polypropylene (PP), polyethylene (PE), ABS, and extruded polystyrene foam (XPS). There are four types of construction methods: RC mesh G-M, earth-retaining plate, stretch film, and cement grout. Electrical characteristics were evaluated by measurements with an impedance analyzer and power transmission experiments of less than 50 W. As a result of the road embedment experiment, even without ferrite and capacitor, the Q factor was nearly 200, and the power of more than 2 kW was obtained at the 91% transmission efficiency at 600 V equivalent value.","PeriodicalId":142939,"journal":{"name":"2021 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124027872","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}

Theoretical principles of bi-directional wireless power are described and an operating chart representing the range of admissible complex voltages induced on the active transmit side is introduced. The implementation is achieved by driving the gate signals of two Class EF coil-drivers from a signal generator, allowing the relative phase of the currents in each coil to be controlled. The rig sets a constant input voltage for each of the two coil-drivers by implementing a source-sink configuration, emulating a bidirectional DC-DC conversion stage at each side. This setup can also be used to test for tuning mismatches and different loading conditions in the back-to-back Class EF configuration. Experimental results include bidirectional wireless power transmission of 20 W across a 13.56 MHz link with 6.56% coupling. The combination of low coupling factors and moderate power levels enables new classes of applications that require large air gaps and tolerance to misalignment such as in micro e-mobility. High efficiency can be maintained despite changes in coupling factors and load since active rectification ensures operation at the resonant point in both tanks.","PeriodicalId":142939,"journal":{"name":"2021 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128606893","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}
