AbstractIn the microwave wireless power transmission in the solar power satellite system, it is important to obtain design data on the power transmission. Major consideration is given to the effect of microwaves on the electromagnetic environment, such as biological bodies, communication channel, and ionosphere. In this paper, the aperture illumination

2017 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW), 2017
For the battery/super-capacitor hybrid system as the wireless power transfer system load, it is rarely discussed. In this paper, the characteristics of such a system are considered, a charging topology is proposed. And a control strategy is proposed to not only meet the requirements of the system energy output, but also maintain the high efficiency of ...

Maximum Tracking Control for Induction Power Taking of 500kV Overhead Transmission Line
2020 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2020The 500kV overhead transmission line induction power supply technology can provide stable and reliable power for high-voltage line online equipment and inspection robots. Since the magnitude of the induced current induced in the ground wire is small, in order to make full use of the induced energy, the principle of impedance matching can be used ...

On the Effects of Maximum Transmission Unit in Power Line Communication Networks
2007 IEEE International Symposium on Power Line Communications and Its Applications, 2007Currently, in many power line communication networks, the maximum packet size for the PLC protocol used to send data, in the interest of obtaining the maximum possible throughput. However, electrical noise on the power lines can cause poor performance for large packet sizes.

Maximum Power Transmission Between Two Reflector Antennas in the Fresnel Zone
Bell System Technical Journal, 1971Power transfer between two ellipsoidal reflector antennas with common focal points and dual-mode feeds has been investigated. Assuming a circularly symmetric feed pattern, the H-plane pattern of an open-end circular waveguide excited by the TE 11 mode, the maximum transmission coefficient between reflector apertures is found to be within 0.5 percent ...

Gating factor analysis of maximum power reduction in multicluster LTE-A uplink transmission
2013 IEEE Radio and Wireless Symposium, 2013In radio frequency (RF) power amplifiers (PA), power efficiency, linearity and cost are contradictory requirements. In the Long Term Evolution (LTE) and LTE-Advanced (LTE-A) standards by the Third Generation Partnership Project, maximum power reduction (MPR) is used to relax RF PA requirements in user equipment.

IEEE Transactions on Wireless Communications, 2017
This paper evaluates the energy efficiency of uplink transmission in heterogeneous cellular networks (HetNets), where fractional power control (FPC) is applied at user equipments (UEs) subject to a maximum transmit power constraint. We first consider an arbitrary deterministic HetNet and characterize the properties of energy efficiency for UEs in ...
