12-Pulse LCI Synchronous Drive for a 20 MW Compressor - Modeling, Simulation and Measurements.

Jean-Jacques Simond, Mai Tu Xuan, Roland Wetter, Alain Sapin

The current source thyristor inverter is still today a suitable choice for supplying high power adjustable speed drives for pumps or compressors. This paper presents a 12-pulse LCI (load commutated inverter) synchronous drive for a 20 MW compressor, it foc ...

An exact formula for "tooth-to-tooth" permeance

Yves Perriard, Marcel Jufer, Miroslav Markovic

We present a new, completely original exact method to determine the permeance between two opposing iron teeth. This configuration is important because it is often encountered in electrical machines and apparatus. The method is based on conformal mapping. T ...

Batch-Type Millimeter-Size Transformers for Miniaturized Power Applications

Martinus Gijs, Farid Amalou

We have developed a novel batch-type technology for making three-dimensional (3-D) millimeter-sized transformers for ultrasmall low-power (0.1 to 1 Watt) applications. The technology uses the 3-D micropatterning of ferrite wafers by powder blasting to form ...

Warped compactification on Abelian vortex in six dimensions

We consider the possibility of localizing gravity on a Nielsen-Olesen vortex in the context of the Abelian Higgs model. The vortex lives in a six-dimensional space-time with negative bulk cosmological constant. In this model we find a region of the paramet ...

Printed circuit board integrated fluxgate sensor

Martinus Gijs

We have developed a cheap and simple trilayer printed circuit board (PCB)-based technology, adapted for the fabrication of fluxgate magnetic sensors. The two outer layers of the PCB stack comprise the electrical windings of the fluxgate, while the inner la ...

A New Hybrid Technology for Planar Fluxgate Sensor Fabrication

Martinus Gijs

We have adapted a new printed circuit board (PCB) technology to the fabrication of ultraflat and sensitive fluxgate magnetic field sensors. The two outer layers of the PCB stack compose the electrical windings of fluxgates, while the inner layer is made of ...

Development of Ag-sheathed Bi(2223) tapes with oriented filaments

Francesco Grilli

Ag-sheathed (Bi,Pb)2Sr2Ca2Cu3O10 tapes have been developed with a special filament configuration that can be of great interest when a magnetic field is applied to the tape at a significant angle with respect to the a–b planes of the superconductor. The fab ...
