Determination of thyristor reverse recovery current parameters

IEE Proceedings B Electric Power Applications, 1988
This paper describes a method of determination of reverse recovery current parameters of the thyristor turnoff model, namely, the peak reverse recovery current and its decay time constant. The parameters are determined from a set of recovered charge curves, and another set of reverse energy loss curves, usually given in the manufacturer's data sheet so

Spontaneous recovery or evoked reversal of neuromuscular block

Acta Anaesthesiologica Scandinavica, 1995
Recovery from the effects of muscle relaxants can occur either spontaneously by their metabolism in the body or by elimination via the normal excretion pathways, or by the administration of pharmacologic antagonists. The decision as to whether spontaneous recovery should be allowed to take place or pharmacologic reversal should be induced depends upon ...

A reverse engineering toolkit for design recovery

1996 IEEE Aerospace Applications Conference. Proceedings, 2002
Migration of code from an imperative paradigm to other paradigms, including the parallel/distributed paradigm, is often done in an ad hoc manner. In order to systematically approach this problem, we first need the design of the original system. In this paper we describe a reverse engineering toolkit that we developed to extract the design of a system ...

Reverse recovery of a GaAs optoelectronic thyristor

Journal of Applied Physics, 1996
Results of numerical simulation of reverse recovery processes in a two-terminal GaAs optothyristor are presented. In the highly conducting ON state there are many excess carriers in the inner layers of the device. Reversing the anode voltage removes these carriers, turning the device off.

Reverse recovery processes in silicon power rectifiers

Proceedings of the IEEE, 1967
The present review gives an account of a number of investigations that have been recently carried out in the Semiconductor Laboratory Pretzfeld, Siemens AG. The switching processes in power rectifiers from the forward into the reverse state differ greatly from the corresponding process predicted by low-level theory.

Reversible Complexes for the Recovery of Dioxygen

1988
Dioxygen 1s produced 1n tonnage quantities by the distillation of air at cryogenic temperatures. In recent years, alternative technologies have emerged that employ O2- or N2-select1ve sorbents or O2-permselectlve polymer membranes. New transition metal complexes that can bind O2 reversibly and with high specificity may provide the basis for even better

Recovery of Recombinant Marburg Virus by Reverse Genetics

Reverse genetics systems can be used to study parts or all of the viral life cycle. Recovery systems are reverse genetics systems used for the generation of infectious recombinant viruses that can carry targeted mutations or express reporter genes.

Reversal of fortune: understanding the Midwest recovery [PDF]

, 1997
Has the Midwest been good or lucky in its recent recovery? In this article, the authors assess the internal and external factors that have contributed to the revival of midwestern economic fortunes over the last decade.
