Configurable Circuits Featuring Dual-Threshold-Voltage Design With Three-Independent-Gate Silicon Nanowire FETs

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Xifan Tang, Jian Zhang

Silicon nanowire transistors with Schottky-barrier contacts exhibit both n-type and p-type characteristics under different bias conditions. Polarity controllability of silicon nanowire transistors has been further demonstrated by using an additional polari ...

Study on the 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 NPC (neutral point clamped) structure and the series-parallel connection of converters. The key property of the proposed topology is the o ...

Generalised space vector PWM for sinusoidal output voltage generation with multiphase voltage source inverters

Drazen Dujic

The paper presents a generalised approach towards the development of the space vector pulse width modulation (SVPWM) for sinusoidal output voltage generation with two-level multiphase voltage source inverters (VSIs), where the number of phases is an odd nu ...

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 ...

A General PWM Method for a (2n + 1)-Leg Inverter Supplying n Three-Phase Machines

Drazen Dujic

Control of an ac machine requires only two currents. It is, therefore, possible to achieve independent control of a number of three-phase machines using various inverter topologies with a reduced switch count. One such drive system comprises n three-phase ...

New self-switching mechanisms for active bidirectional switches

Alfred Rufer, Philippe Barrade, Daniel Siemaszko

The self-switching principle is a synthesis of synchronous type switching and switch inner protection mechanisms. Both switch ON and switch OFF are performed on the base of current and voltage measurement across the switch. Applied to an active bidirection ...

Modeling, Simulation, and Test of a Three-Level Voltage-Source Inverter With Output LC Filter and Direct Torque Control

Jean-Jacques Simond, Alain Sapin

This paper presents the modeling, detailed simulation, and test of an efficient medium-voltage adjustable-speed drive. The system consists of a three-level neutral-point-clamped inverter supplied by a 12-pulse rectifier. To achieve a motor-friendly supply, ...
