Graphene actively Q-switched lasers
(2017-05-05)
Graphene electro-optic modulators (GEOMs) are emerging as a viable alternative to conventional material-based modulators mainly due to their broadband and ultrafast performance. These GEOMs with combined advantages of small ...
Improving performance of switched reluctance motor by fuzzy logic controller
(1999-04)
This paper presents torque ripple minimization of a switched reluctance motor (SRM) by using a fuzzy controller, The nonlinear model of the SRM and the mathematical model of the converter circuit are driven. The motor used ...
New architectures for space power systems
(IEEE, 1995-08)
Electric power generation and conditioning have experienced revolutionary development over the past two decades. Furthermore, new materials such as high energy magnets and high temperature superconductors are either available ...
Magnetically inflatable SPS with energy storage capability
(IEEE, 1995)
A new approach to superconductive magnetic energy storage (SMES) for solar power satellite (SPS) with inherent rigidity is introduced in this paper. The rigidity of this SMES originating from the electromagnetic forces ...
TEM Wave Scattering by a Step Discontinuity on the Outer Wall of a Coaxial Waveguide
(2013-08)
In this paper, the propagation of TEM waves along a coaxial waveguide with a step discontinuity on its outer wall is investigated rigorously by applying the direct Fourier transform and reducing the problem into the solution ...
Power converters as natural gyrators
(IEEE, 1993-12)
The authors investigate the open-loop gyrator behavior of a class of DC-DC converters that are characterized by double bridges. If the switching frequency of the double bridge converter is high enough with respect to its ...
Inverse dual converter (IDC) for high power DC-DC applications
(IEEE, April 1993)
A family of DC-DC converters suitable for high-power applications is introduced. The inverse dual converter (IDC) is capable of continuous voltage step-up or step-down control over a wide range of and without the need of ...
Capacitor coupled converter (C3) for high power DC conversion
(IEEE, 1995)
The bang-bang controlled capacitor coupled converter (C<sup>3</sup>) is described in this paper. Due to the converter's inherent commutating property, the C<sup>3</sup> can accommodate thyristors as well as high-power gate ...
Fuzzy logic based control of switched reluctance motor to reduce torque ripple
(IEEE, 1997)
This paper presents torque ripple reduction of a switched reluctance motor (SRM) by using a fuzzy speed controller. For this purpose, current control is applied with a fuzzy speed controller. The fuzzy controller adjusts ...
Texture Analysis Based Iris Recognition
(2006-01)
In this paper, we present a new method for personal identification, based on iris patterns. The method
composed of iris image acquisition, image preprocessing, feature extraction and finally decision
stages. Normalized ...
