A DC power flow extension

Maher Kayal, Theodoros Kyriakidis

In this work an extension of the well-known DC power flow method is presented. A normal DC power flow of the system is executed to determine voltage angles and a novel derivation of voltage amplitudes is devised. The latter is rigorously formulated and eig ...

Power Quality Application of Hybrid Drivetrain

Hardi Hõimoja

This paper presents a study on the power conditioning features of hybrid powertrain, especially regarding diesel-electric locomotives. Equipped with an embarked energy buffer for diesel generator support and utility grid interface, such a locomotive can be ...

Controlling a Single DNA Molecule in an Electric Field by Means of In Situ Atomic Force Microscopy

Giovanni Dietler, Jae Sun Jeong

DNA is the bio-polymer containing the genetic information needed for the development and functioning for all living organisms. It has a polymeric structure consisting of units called nucleotides, each consisting of a non-polar, hydrophobic interior (the ba ...

Quantum Point Contact Microscopy

Klaus Kern, Peter Wahl

We introduce quantum point contact microscopy (QPCM) as a novel method for surface characterization, where the conductance through a quantum point contact formed by a metal atom between the tip of a scanning tunneling microscope and the surface is mapped a ...

Full platinum nanoprobes for electrically conducting scanning probe methods

Jürgen Brugger, Johannes Steen

Recently electrically conducting SPM probes were used as read/write sensor of magneto-resistive nanopillars and ferroelectric domains in the development of >1 Tb/inch2 data storage. Since metal coated (platinum (Pt) or Pt/iridium) silicon (Si) probes are n ...

Investigation of Interactions Between Co-fired LTCC Components

Peter Ryser, Thomas Maeder, Caroline Jacq, Hansu Birol

In spite of many advantages it offers for micro-electronic packaging, the low temperature co-fired ceramic (LTCC) technology has yet certain issues to be solved. Physical and chemical reactions, for instance, within and between the passive electronic compo ...

Investigation and control of a hybrid asymmetric multi-level inverter for medium-voltage applications

Martin Veenstra

Power-electronic inverters are becoming popular for various industrial drives applications. In recent years also high-power and medium-voltage drive applications have been installed. However, the existing solutions suffer from some important drawbacks. Hyb ...

Study of probes and substrates for low temperature atomic force microscopy and biological applications

Giovanni Dietler, Aleksandra Radenovic

The atomic force microscopy in ultrahigh vacuum and at low temperature demonstrated its excellent capability to reach atomic resolution. Nevertheless in the case of biological samples high resolution has been achieved only in very few cases. We demonstrate ...

Modification of brushless DC motor back-EMF shape-application to noise reduction

Yves Perriard

The brushless DC motors are normally built with rotor mounted PMs, which create the necessary back EMF voltage to produce a mechanical power. The shape of this back-EMF voltage is very important compared to the phase voltage supply one. Indeed, the electro ...
