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.

Energy Efficiency Evaluation of Uplink Transmissions with Maximum Power Constraint
2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017Energy efficiency of uplink users is critical for evaluating the energy consumption of heterogeneous cellular networks (HCNs) with heavy loading. The energy efficiency of user equipments (UEs) in HCNs depends heavily on power control scheme as well as maximum power constraint.

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.

Sliding Mode Control of an Inductive Power Transmission System with Maximum Efficiency
2021 18th International Multi-Conference on Systems, Signals & Devices (SSD), 2021Sliding mode control (SMC) is used to regulate the output power of an inductive power transfer (IPT) system with maximum efficiency tracking. Load variations and misalignment are the main factors that affect the output power and efficiency of the system.

Sensitivity Studies of Compensated EHV Transmission Line for Maximum Power Transfer
Electric Power Components and Systems, 2003The sensitivity analysis of EHV transmission lines compensated with series capacitors and shunt reactors is attempted to observe a priori the effects of several line parameters on load-end VAR source compensation for different loadings. The sensitivity study is also applied to the probabilistic evaluation of the load-end VAR source compensation.

Transmission-Line Class-E Power Amplifier With Extended Maximum Operating Frequency
IEEE Transactions on Circuits and Systems II: Express Briefs, 2011A novel Class-E power amplifier (PA) topology with transmission-line load network is presented in this brief. When compared with the classic Class-E topology, the new circuit can increase the maximum operating frequency up to 50% higher without trading the other Class-E figures of merit.

Maximum power transfer in AC transmission lines limited by voltage stability
Proceedings of International Conference on Power Electronics, Drives and Energy Systems for Industrial Growth, 2002Closed form expressions for the maximum power transfer, limited by voltage stability and the corresponding voltage, in AC transmission lines for constant power and constant impedance type loads are derived. The transmission line is represented by its n-equivalent model.
