Risk Evaluation for Hybrid Excitation Compulsator

IEEE Transactions on Plasma Science, 2015
In the field of compulsators, hybrid excitation concepts have been verified through the development of several hybrid excitation prototypes. Although there are some advantages associated with the hybrid excitation compulsator in comparison with the traditional electrical excitation topology compulsator, some drawbacks still exist, which may lead to ...

Hybrid Hamiltonian Simulation for Excitation Dynamics

The Journal of Physical Chemistry Letters
Hamiltonian simulation is one of the most anticipated applications of quantum computing. Quantum circuit depth for implementing Hamiltonian simulation is commonly time dependent using Trotter-Suzuki product formulas so that long time quantum dynamic simulations (QDSs) become impratical for near-term quantum processors.

Parametric excitation of lower hybrid instabilities

The Physics of Fluids, 1973
The application of a sufficiently intense long wavelength oscillating electric field at the lower hybrid frequency to a plasma with two ion species leads to instability of finite wavelength electron-ion lower hybrid modes and a purely growing modification of the ion-ion hybrid mode.

Double disc alternators with hybrid excitation

IEEE Transactions on Magnetics, 1992
The authors investigate a version of a double disc alternator which uses both a stationary coil on the armature side of the airgap and permanent magnets on the rotor side for excitation. The machine is brushless without the use of rotating diodes, but nevertheless can be voltage regulated.

Efficient Event-Driven Simulation of Excitable Hybrid Automata

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
We present an efficient, event-driven simulation framework for large-scale networks of excitable hybrid automata (EHA), a particular kind of hybrid automata that we use to model excitable cells. A key aspect of EHA is that they possess protected modes of operation in which they are non-responsive to external inputs.

Excitation of lower-hybrid waves in dusty plasmas

Journal of Plasma Physics, 2005
A dispersion relation is derived detailing the effect of a population of charged dust grains on the growth of lower-hybrid waves excited by a, ring distribution of ions in a plasma. Numerical solutions show that the instability can be enhanced or reduced depending on the parameter regime.

Flux regulation strategies for hybrid excitation synchronous machines

2014 IEEE Energy Conversion Congress and Exposition (ECCE), 2014
This paper investigates methods to achieve a wide constant power speed range (CPSR) in electric drives using hybrid excitation synchronous machines; five strategies are presented and compared. These range from state-of-the-art flux weakening based on demagnetizing armature current injection, to algorithms based on wound excitation (WE) current ...

Hybrid excited claw pole electric machine

2016 21st International Conference on Methods and Models in Automation and Robotics (MMAR), 2016
The paper presents the concept and results of simulation and experimental research of a claw pole generator with hybrid excitation. Hybrid excitation is performed with a conventional coil located between two parts of the claw-shape rotor and additional permanent magnets which are placed on claw poles.
