Modeling of parasitic oscillations in smooth-wall circular symmetric dielectric-loaded gyrotron beam ducts

Stefano Alberti, Jean-Philippe Hogge, Jérémy Genoud

The self-consistent simulation of the electron beam interaction was performed in the presence of a lossy dielectric layer in the smooth-wall beam duct of a gyrotron oscillator. For this purpose, the linear and spectral code TWANGlinspec was extended. In th ...

Negative Capacitance as Universal Digital and Analog Performance Booster for Complementary MOS Transistors

Mihai Adrian Ionescu, Christian Enz, Igor Stolichnov, Farzan Jazaeri, Ali Saeidi

Boltzmann electron energy distribution poses a fundamental limit to lowering the energy dissipation of conventional MOS devices, a minimum increase of the gate voltage, i.e. 60 mV, is required for a 10-fold increase in drain-to-source current at 300 K. Neg ...

A Study of a Large Bipolar Lightning Event Observed at the Säntis Tower

Marcos Rubinstein, Mohammad Azadifar, Wolfgang Schulz, Davide Pavanello

An unusual negative lightning flash was recorded at the Säntis Tower on June 15, 2012. The flash did not contain an initial continuous current typical of upward negative lightning, which is the most common type of event at the Säntis Tower. The flash conta ...

Measurement of Large-Signal Coss and Coss Losses of Transistors Based on Nonlinear Resonance

Elison de Nazareth Matioli, Armin Jafari, Palliyage Srilak Nirmana Perera

In this letter, we present a new measurement technique to evaluate the large-signal output capacitance ( COSS ) of transistors as well as the COSS energy dissipation ( EDISS ), based on the nonlinear resonance between a known inductor and the output capaci ...

Input-Admittance Passivity Compliance for Grid-Connected Converters With an LCL Filter

Drazen Dujic, Francisco Daniel Freijedo Fernández, Enrique Rodriguez Diaz

This work presents a design methodology and its experimental validation for the input-admittance passivity compliance of LCL grid-connected converters. The designs of the LCL filter parameters and discrete controller are addressed systematically, and suita ...

Critical Parasitic Elements of Coupled Inductors for Ultra-High Voltage Flyback Converters Used to Drive Capacitive Actuators

Yves Perriard, Alexis Boegli, Morgan Almanza, Raphaël Johannes Charles Mottet

This paper presents the critical parasitic elements of coupled inductors and their influence when designing a low input (12V) and ultra-high output voltage (>4000V) DC-DC Flyback Converter. The aim is to design a compact converter capable to supply the ult ...
