Roadway powered electric vehicles with minimum onboard stored energy can offer a solution for the limited cruising range problem of electrical vehicles. This work provides a design study of a moving field inductive power transfer (MFIPT) system based on stationary primary coils linearly arranged along one or several tracks of a roadway and a secondary coil in each vehicle. Due to the unavoidable large spacing between primary and secondary coils, these coils are only loosely coupled. The resulting leakage inductances have to be compensated by capacitors. To minimize power loss only the primary coils under the vehicles are activated. In the MFIPT system the primary coils are operated as a switched resonant converter. When switching from one primary coil to the subsequent primary coil on the track in order to follow the moving vehicle the electric and magnetic energies stored in the coils and capacitors are passed on to the subsequent coils and capacitors in order to avoid loss of the stored energy.

In the conventional resonator-coupled WPT system, coil resonators made of copper wire are usually used. So, unloaded Q of coil resonator is a few hundred to one thousand due to metal conductivity. There is a limit for transmission distance due to the loss caused by low unloaded Q of the coil resonator. In this study, the authors propose a novel WPT system using ceramic dielectric resonators. Unloaded Q of dielectric resonator is several tens of thousands depending on the material. Thus, we can expect much longer transmission distance by using ceramic resonator.

In this paper, a wireless power transfer system (WPT) with magnetically coupled resonators is studied. The idea to use a reflector to enhance the coupling coefficient and the transfer efficiency is proposed and analyzed. Perfect magnetic conductor (PMC) was used in numerical calculations in order to study the performance of a reflector. In the WPT system we studied, efficiency is increased from 48% without reflector to 72% with PMC reflector. With recently developed metamaterial technologies, artificial PMCs can be designed and fabricated for such reflectors.

This paper demonstrates fundamental evaluation results of a C-band rectifier using GaAs high-electron mobility transistor (HEMT) for microwave power transfer (MPT) inside of future reusable rockets. Rectifiers which utilize HEMT MMICs with hot-via interconnection structure are feasible solution to integrate with conventional wireless communication MMICs or sensor tags for low cost, light weight, and small components for space health monitoring system. Simulation of large signal S-parameters, measurement of rectification efficiency are conducted as a fundamental evaluation. Maximum rectification efficiency of 51.3 % at 5.1 GHz while the load resistance is 350 Ω is obtained from the measurement.

Capacitive power transfer has many important merits including less heating, less effect from metal barriers and more material options. But its positional characteristics had not been studied quantitatively and generically enough. This study analyzed the capacitive power transfer with the same manner as magnetic resonance. The analysis on the equivalent circuit model showed the positional characteristics of the efficiency are determined by coupling coefficient as in magnetic resonance. The coupling coefficient simulation showed the effective range is as long as that of magnetic resonance along the distance and is longer along the one of misalignment directions.

This paper compares a 4-by-4 dipole staggered pattern charge collector (SPCC) rectenna array to a 16 dipole rectenna array arranged in a four series-four parallel configuration. While each of these energy harvesting circuits has an identical footprint, the SPCC has a DC power pattern which simultaneously provides high gain and wide beamwidth. This profile provides RF energy harvesting sensors with additional range and makes them less sensitivity to orientation. At 0.1 m range, the N2 rectenna has a peak DC voltage 20% larger than the SPCC, but the SPCC's beamwidth is 400% larger than the N2 rectenna array. At 1 m range, the SPCC beamwidth is 600% larger, and the peak voltage is 300% larger than the N2 rectenna control case.

The system has been designed so that it can be embedded into the structure without compromising its mechanical properties. Results will demonstrate that high amounts of power can be transmitted to the embedded system while fulfilling the different project requirements. Finally, it will be demonstrated that a parallel data transmission is also possible.
