Improving the efficiency of the IPT systems through power electronics and control has become a focus to make IPT competitive to the existing contact power transfer solutions. This paper reviews and evaluates the state-of-the-art IPT control methods and proposes an optimal operation point tracking control for the IPT system. The proposed method controls the switching frequency, transmitter and receiver PWM duty-cycles to compensate for changes in gap distance, coil misalignment, temperature and component parameter tolerance. The optimal operation points are tracked to improve the overall system efficiency. The proposed method is analyzed by comparing the different operating points at power and efficiency curves of the IPT system. Furthermore, a 4.5 kW IPT prototype is designed and three control strategies are implemented and tested in the IPT prototype. The experimental results verified that the proposed optimal operating point method effectively improves the system efficiency and tolerance to environment variables.","PeriodicalId":194427,"journal":{"name":"2015 IEEE Wireless Power Transfer Conference (WPTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129454394","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 transmission frequency was set to 430 MHz to keep the antenna small (relative to an antenna for the SHF region) and to enable the use of inexpensive off-the-shelf rectifiers. The system can supply power to multiple targets within the beam angle of the transmitting antenna. A self-rotating quadcopter rotor unit (rotor, antenna, rectifier, filter, two motors) weighing less than 5.5 g was developed. A patch-array-style beam antenna for power transmission with a sufficient gain and radiating over a large enough area for multiple nearby targets was also designed. A quadcopter with four rotor units was tested: It hovered about 10 cm above the transmitting antenna, which was driven by 30 W of RF power at a frequency of 430 MHz. The four rotor units received a maximum power of 6 W, yielding a transfer efficiency of around 20%.","PeriodicalId":194427,"journal":{"name":"2015 IEEE Wireless Power Transfer Conference (WPTC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126581632","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 if the devices are not all the same size or if they require different amounts of power, these existing standards may be incapable of charging multiple devices efficiently. This paper provides an overview of a complete wireless power transfer system that is capable of automatically tuning, communicating with, and efficiently powering multiple single-cell battery charging receive devices. Frequency tracking, power tracking, and adaptive impedance matching are used to dynamically tune each receiver and the transmitted signal for optimal power delivery to each receiver. Additionally, these same tuning techniques are used to demonstrate time-division multiplexing, where individual receive devices are powered sequentially while all other receive devices are de-tuned and do not consume any power, even in the presence of the transmit coil.","PeriodicalId":194427,"journal":{"name":"2015 IEEE Wireless Power Transfer Conference (WPTC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128273265","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}

Safe exposure limits should be maintained, and protective housing and padding are generally needed; however, these impose compromises on the power-transfer-system design. This paper analyses these trade-offs and proposes a design route to achieving high power transfer in the presence of field restrictions and separations for padding or housing materials. An IPT system using a Class D coil-driver and switched-mode power-conditioning is designed to provide regulated d.c. and energy storage. Compliance with ICNIRP 1998 guidelines is demonstrated, at a power level that is sufficient to power typical on-body medical sensing devices.","PeriodicalId":194427,"journal":{"name":"2015 IEEE Wireless Power Transfer Conference (WPTC)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133920092","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}

Our analytical and numerical results show that by using large transmitter arrays, the range of wireless power transfer can be increased while maintaining a target outage probability.

The WPT leakage emulator that can generate the electromagnetic field leaked from the WPT system is used in the measurement. The suitable calculation algorithms with respect to three frequency bands that cover the high-harmonic component of the leaked electromagnetic field are applied for the simulation.

A prototype platform operating at 13.56 MHz is designed and fabricated and the capability of the PSO to tune the system to the operating point of maximum efficiency is demonstrated by experiments.
