The basic cell operating regimes for wireless Power Transfer of Electric Vehicles

, 2016
In this work we concentrate on the two possible regimes at which wireless power transfer can be attained. One regime allows to maximize either the power on the load or the efficiency, at a given fixed frequency, by changing the load value. Another regime

Design of excitation current estimation algorithm for wireless excitation system of electrically excited motors based on S-N resonant topology

Wireless Power Transfer
Although wireless excitation improves the reliability of electrically excited synchronous motors (EESMs), the rotor field current cannot be directly measured due to the rotation of the rotor.

Controlled Growth of Boron Nitride in Various Phases

Advanced Materials Interfaces, EarlyView.
Phase‐selective boron nitride growth is presented as a unified materials‐design problem across hexagonal, rhombohedral, cubic, and amorphous phases. By linking synthesis routes to thermodynamic stability, kinetic accessibility, surface diffusion, interfacial templating, and energetic activation, this review clarifies how bonding and stacking are ...
