Maximum Available Power of Undersea Capacitive Coupling in a Wireless Power Transfer System [PDF]

, 2021
This paper studies the maximum available power of a dissipative capacitive power transfer (CPT) system submerged in seawater. The CPT system's maximum power capability is driven using the network theory, precisely the conjugate-image approach.

A wireless power transfer system for electrical vehicles exploiting magnetically coupled resonance and a tapped capacitance impedance transformer [PDF]

, 2014
The input impedance of a wireless power transfer system is heavily influenced by variation of the load impedance, distance between coils and presence of any massive conducting or shielding structures that may exist around the system.

Discontinuous phasor model of an inductive power transfer system [PDF]

, 2017
Recently, a new discontinuous phasor transform has been introduced. The discontinuous phasor can represent the steady-state quantities of electrical circuits powered by discontinuous sources (e.g. square waves) without approximations.

A Framework for Qualitative Analysis of Voltage Stability Indices (VSIs)

IEEE Access
Voltage stability assessment (VSA) is invariably an essential step in the satisfactory operation of power system. For this, several Voltage Stability Indices (VSIs) based on 1) Existence of solution for voltage equations, 2) Maximum power transfer (MPT ...

Modal Analysis of Light Propagation, Polarization and Diffraction by Cholesteric Liquid Crystal Layers

Advanced Functional Materials, EarlyView.
The analysis of optical eigenmodes in chiral liquid crystal with perpendicular or tilted helical axis, and their correspondence with the external medium, leads to an intuitive understanding of the angle and wavelength dependency of transmissive and reflective diffraction.
