Advanced EMI input filtering for an industrial power supply with a resonant stage

Drazen Dujic

Different EMI filters have been designed for an industrial power electronic converter system and a study on the performance of these different input filter topologies has been performed. Based on one filter topology a study on the influence of the orientat ...

Power Distribution Solutions for Large Hadron Collider Upgrades

Stefano Michelis

In view of the Large Hadrons Collider experiments upgrade, where the inner front-end electronics will require higher supply power, a new power distribution scheme has to be designed. This thesis presents a new and more efficient scheme based on step-down D ...

Multilevel two quadrant DC/DC converter for regenerative braking in mobile applications

Alfred Rufer, Daniel Montesinos Miracle

In this paper different cascaded and multilevel topologies are compared for regenerative braking systems using supercapacitors (SC). It shows that the multilevel buck derived topology can beneficiate from both reduced voltage across the inductor and increa ...

On The Possibility Of Using A Heavy Ion Beam Probe For Local Poloidal Flux Measurements In A Tokamak

Henri Weisen

This paper examines the possibility of using the principle of conservation of canonical momentum applied to heavy ion beam orbits to obtain an estimate of the local poloidal flux at the position of ionization in a tokamak plasma. The presence of a nonaxisy ...

Design methodology and comparison of rectifiers for UHF-band RFIDs

Catherine Dehollain, Francesco Mazzilli, Norbert Jöhl

Rectifiers are important energy converters and henceforth crucial building blocks for RFID applications. In the first half of the work, we have presented a design methodology for matching the rectifier input impedance with the antenna to maximize the recti ...

A Slew Controlled LVDS Output Driver Circuit in 0.18um CMOS Technology

Seyed Armin Tajalli, Yusuf Leblebici

This article presents a power-efficient low-voltage differential signaling (LVDS) output driver circuit. The proposed approach helps to reduce the total input capacitance of the LVDS driver circuit and hence relaxes the tradeoffs in designing a low-power p ...

On performance of series connected CMOS vertical hall devices

Radivoje Popovic, Mirjana Banjevic

Series connected (stacked) CMOS vertical Hall devices were analyzed on the basis of performance of a single five contacts device biased at different common mode voltages with respect to the substrate. The uneven influence of junction field effect on residu ...

Electromagnetic compatibility of power line communication systems

Ana Vukicevic

The power system has been used for communication purposes for many decades, although it was mainly the power utility companies that used low bit rates for control and monitoring purposes. In the last ten years, however, the deregulation of the power and te ...

Dedicated controller design for a dual-stage opto-mechatronic system

Denis Gillet, Philippe Müllhaupt, Yvan Michellod

To improve the resolution of the Very Large Telescope Interferometer (VLTI) a two-stage mechanical system, a so called Differential Delay Line (DDL), is developed jointly by the EPFL and the Observatory of Geneva. The system is designed to reach nanometer ...
