Maximum Active Power Transmission Efficiency and Apparent Power Definition with Arbitrary Waveforms
European Journal of Electrical Engineering, 2022A proof of the theorem giving the maximum available active power with constant transmission losses (i.e., maximum efficiency) valid for arbitrary waveforms, is proposed. This makes it possible to rigorously generalize the definitions of power factor based on the definition of apparent power as the maximum power available to apply them to systems with ...

Electronics and Communications in Japan (Part I: Communications), 1983
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

Optimizing Viscosity for Maximum Power in a Hydrostatic Transmission Wind Turbine
BATH/ASME 2022 Symposium on Fluid Power and Motion Control, 2022Abstract In basic hydraulic theory, efficiency is dependent on volumetric and mechanical losses. Components dominated by mechanical losses favor low viscosity fluids, while those dominated by volumetric losses favor high viscosity fluids. For a hydrostatic transmission (HST), efficiency of both the pump and motor must be considered.

Maximum Power Transmission in Mass-Limited Radio Systems
IEEE Transactions on Communications, 1982A simple fundamental relationship is derived between antenna gain and transmitter power which maximizes the effective radiated power in mass-limited satellite systems. In the most common case, maximum effective radiated power is achieved when the payload mass is divided equally between the antenna system and the power system.

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.

Wind turbine electrohydraulic transmission system control for maximum power tracking with pump fault
Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2023The wind power generation system plays a significant role in the power sector as it is an environment-friendly green power system, increasing power demand, and technological development in wind power systems. Wind turbine systems are exposed to the harsh environment with continuous variation of wind speed with gusts causing damage and failure in system

Upgrading AC transmission to DC for maximum power transfer capacity
2008 12th International Middle-East Power System Conference, 2008The paper describes current developments for upgrading of existing AC transmission lines for substantial increase in power transfer capacity by a new concept of conversion to HVDC transmission. Traditionally, such a conversion has been contemplated as being three phase AC to bipolar DC.

Power Allocation for Maximum Effective Transmission in Cooperative FSO Networks
2018 Asia Communications and Photonics Conference (ACP), 2018Although Free Space Optical (FSO) system is an effective solution for high-rate transmission, it is sensitive to the environment. To combat weather turbulence, cooperative FSO system is proposed to promote diversity gain. Power allocation is an important issue in cooperative FSO system, which impacts the system throughput and reliability. In this paper,

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.
