An EMTP system level model of the PMAD DC test bed [PDF]

open access: yes
A power management and distribution direct current (PMAD DC) test bed was set up at the NASA Lewis Research Center to investigate Space Station Freedom Electric Power Systems issues. Efficiency of test bed operation significantly improves with a computer

Nuclear Magnetohydrodynamic EMP, Solar Storms, and Substorms

open access: yes, 2003
In addition to a fast electromagnetic pulse (EMP), a high altitude nuclear burst produces a relatively slow magnetohydrodynarnic EMP (MHD EMP), whose effects are like those from solar storm geomagnetically induced currents (SS GIC).

High-frequency transient suppression in the distribution network: analysis and performance enhancement of an intelligent switch protection on-column

open access: yesJournal of King Saud University: Engineering Sciences
Adjacent feeder column switches in electrical distribution systems may malfunction or refuse to operate during fault line isolation due to the rapid propagation of fault current.

Modelling and simulation of power electronic systems using a bond graph formalism [PDF]

open access: yes, 2010
This paper deals with the modelling of power electronic systems using the bond graph formalism. The switching components are modelled using an ideal representation so that a constant topology system is obtained. The purpose of the present contribution is
