Active lamp pulse driver circuit [PDF]
, 1983 A flashlamp drive circuit is described which uses an unsaturated transistor as a current mode switch to periodically subject a partially ionized gaseous laser excitation flashlamp to a stable, rectangular pulse of current from an incomplete discharge of ...

Numerical analysis of switching performance evaluators in low-voltage switching devices
, 2015 An arc modelling is a valuable and useful tool to evaluate the switching performance of low-voltage switching devices (LVSDs) during breaking operation before testing real products. Moreover, it helps improve interruption capability of LVSDs and optimize

Planar Detonation Wave Initiation in Large-Aspect-Ratio Channels [PDF]
, 2006 In this study, two initiator designs are presented that are able to form planar detonations with low input energy in large-aspect-ratio channels over distances corresponding to only a few channel heights. The initiators use a single spark and an array of

A Novel Approach to Power Circuit Breaker Design for Replacement of SF6
Acta Polytechnica, 2004 This contribution explores the role of PTFE ablation in enhancing current interruption for various background gases in high voltage circuit breakers. An assessment of the current interruption capability has been made in terms of the arcing duration and ...

Type Ia supernovae from exploding oxygen-neon white dwarfs [PDF]
, 2015 The progenitor problem of Type Ia supernovae (SNe Ia) is still unsolved. Most of these events are thought to be explosions of carbon-oxygen (CO) white dwarfs (WDs), but for many of the explosion scenarios, particularly those involving the externally ...

Investigation of hydrogen-air ignition sensitized by nitric oxide and by nitrogen dioxide [PDF]
The sensitization of stoichiometric hydrogen-air ignition by NO, NO2 and a mixture of NO and NO2 was investigated behind reflected shock waves in a shock tube. Induction times were measured in pressure range 0.27 to 2.0 atm, temperature range 800 to 1500
