OTH-WPT may also be feasible in the LWIR particularly at 10.6 microns, a wavelength that has advantages in terms of mature transmitter technology, laser eye safety, and less deleterious atmospheric effects. Most of the subsystems of OTH-WPT at this wavelength are mature, commercially available technologies. In this article we present the architecture for a 10.6 micron OTH-WPT system. We review the state-of-the art in terahertz rectenna technology and discuss key issues that must be resolved for the feasibility of an OTH-WPT demonstration at this wavelength.","PeriodicalId":194427,"journal":{"name":"2015 IEEE Wireless Power Transfer Conference (WPTC)","volume":"4 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":"133233110","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 high level of reconfiguration of these arrays allows a smart transfer of power by means of a two-step procedure: first the sole two central elements of the array are used for localization purposes, by combining the sum and difference radiation patterns; then the entire 16-element TMA transmits the dedicated power to the detected tags, relying on the fundamental and sideband harmonic radiations. The entire nonlinear radiating systems is accurately described within a circuit-level/full-wave CAD platform: promising simulated results of the smart WPT operation are presented.","PeriodicalId":194427,"journal":{"name":"2015 IEEE Wireless Power Transfer Conference (WPTC)","volume":"99 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":"115341270","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}

With this growing number of deployed devices, there is a necessity to quickly locate and charge them individually. Conventional localization techniques either require intelligence and extra hardware or are limited to merely detecting the presence of an object and not its position. In the proposed localization technique, we use two wireless power transmitters (TX) operating at the the same frequency. The phase difference between the two TXs can be controlled. The forward/reflected signals are measured from each TX and are used to accurately localize the receiver in a two dimensional space. This system does not require additional hardware on the TX or RX side. The entire detection process can be confined to the transmitter firmware. We also formulate a simple localization parameter using the reflected signals to prove the concept of localization.","PeriodicalId":194427,"journal":{"name":"2015 IEEE Wireless Power Transfer Conference (WPTC)","volume":"31 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":"114611858","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 power amplifier driving the power transmitting coils is based on a Class Φ2 inverter, a single switch topology with low switch voltage stress and fast transient response. This implementation utilizes a recently available GaN device in a low inductance package that is compatible with operation in the 10's of MHz switching frequency. These power GaN switching devices have low gate resistance RG and low capacitance CGS which greatly reduces the power requirements of the gate drive circuitry. This paper shows experimental measurements of the inverter in a WPT application and characterization of the system performance over various distances and operating conditions.","PeriodicalId":194427,"journal":{"name":"2015 IEEE Wireless Power Transfer Conference (WPTC)","volume":"188 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":"122585005","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}

In this work, the exploitation of commonly-employed radar signals featuring this high PAPR characteristic is proposed for the first time for the WPT application.

In this paper, introducing the concepts of fixed grid-based coil representation and effective turns, a novel layout optimization is proposed to determine the optimal layout of the secondary coils when the primary coils are given. Using the proposed method, the secondary-coil layouts are successfully determined to maximize the induced voltages while satisfying mass constraints. The optimized layouts are then validated through the experiments under the same conditions.","PeriodicalId":194427,"journal":{"name":"2015 IEEE Wireless Power Transfer Conference (WPTC)","volume":"59 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":"127097118","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}

To reduce the energy requirements of our low voltage boost converter a low power timer is used to trigger the boosting operation. For low input power levels the act of monitoring the input voltage can use more energy than is recovered by the harvester. To extend the range of useful input powers a timer circuit is used to control how often and for how long the boost converter is activated. In this initial proof of concept, a net positive energy balance is achieved at a conducted input power level of -15 dBm at 2.45 GHz, yielding a harvester output voltage of 460mV and a boosted output voltage of 1.8V.","PeriodicalId":194427,"journal":{"name":"2015 IEEE Wireless Power Transfer Conference (WPTC)","volume":"7 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":"125289860","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}
