Ion current rectification and rectification inversion in conical nanopores: a perm-selective view

Hubert Girault, Fernando Cortes Salazar, Dmitry Momotenko

Ionic transport in charged conical nanopores is known to give rise to ion current rectification. The present study shows that the rectification direction can be inverted when using electrolyte solutions at very low ionic strengths. To elucidate these pheno ...

Reversible DC/DC Converter as interface between Low and Medium Voltage DC Networks

Alfred Rufer, Stephan Kenzelmann, Carlo Arrioja

This paper introduces an isolated reversible DC/DC converter with a particular topology, which benefits from both the Neutral Point Clamped (NPC) structure and the series-parallel connection of converters. The key property of the proposed topology is the o ...

Scan-Rate-Dependent Ion Current Rectification and Rectification Inversion in Charged Conical Nanopores

Hubert Girault, Dmitry Momotenko

Herein we report a theoretical study of diode-like behavior of negatively charged (e.g., glass or silica) nanopores at different potential scan rates (1-1000 V center dot s(-1)). Finite element simulations were used to determine current-voltage characteris ...

Investigations on a 1kVA Reactive Power Compensated Current Converter using monolithic RB-IGBT modules

Alfred Rufer, Daniel Siemaszko

This work presents a current converter topology with an added free-wheeling path on the output load. This converter allows the compensation of the reactive power consumption by forcing the input current fundamental component to be in phase with the input v ...

Analysis of Output Current Ripple rms in Multiphase Drives Using Space Vector Approach

Drazen Dujic

Multiphase variable-speed drives, supplied from two-level voltage source inverters (VSIs), are nowadays considered for various industrial applications. Although numerous pulsewidth modulation (PWM) schemes for multiphase VSIs, aimed at sinusoidal output vo ...

Convertisseur de fréquence indirect à rapport de tension fixe

Aziza Benaboud

Many electric power generators use gas turbines as power sources. Typically they are connected to the turbines through a mechanical gearbox in order to adapt their synchronous speed to the optimal rotation speed of the turbine, which is very often much hig ...
