Studying reliability: Cryocoolers and power convertors

AIP Conference Proceedings, 2002
The dynamic machines discussed in this paper are cryocooler and power convertors using various thermodynamic cycles and moving parts. Analyzing dynamic machine reliability has been difficult from the beginning. Classic reliability analyses rely on statistical sampling and comparing failure modes to other similar systems where statistical results are ...

New power convertor technique employing power transistors

Proceedings of the Institution of Electrical Engineers, 1978
A new power convertor, using power transistors in a switching mode as the main power elements, has been introduced. This convertor is capable of conversion from a fixed 3-phase source to variable frequency, controlled output current, such that the operating frequency range is not limited by the supply frequency.

Auxiliary power convertors for locomotives

1980 IEEE Power Electronics Specialists Conference, 1980
The use of squirrel cage motor for auxiliary loads in railroad applications makes it necessary to have a conversion system aboard the locomotive or the train. This system has to convert a 1-phase ac or a dc voltage into a 3-phase 50 or 60 Hz voltage. This paper presents solutions built on power electronics.

Active filters for static power convertors

IEE Proceedings B Electric Power Applications, 1983
The need for output filters with static power convertors is well known. The paper presents a different way of solving the problem. A new configuration is therefore proposed, which includes both active and passive components. The advantages of this system are, among others, that it can be used for both AC and DC convertors, especially where very low ...

Ramptime current control [for power convertors]

Proceedings of Applied Power Electronics Conference. APEC '96, 2002
Ramptime current control is a new robust technique for directly controlling the inductor current in switched power converters. It is largely invariant with respect to circuit parameters and system voltages. Ramptime is a sliding mode method producing zero average current error (ZACE) in each switching period with a controlled switching frequency band ...

Application of power transistors to polyphase regenerative power convertors

Proceedings of the Institution of Electrical Engineers, 1978
An important mode of operation of a general power amplifier using power transistors is described, whose output is a variable-frequency 3-phase current. The convertor operates from a fixed 3-phase source without a d.c. link, utilises only 18 power transistors and provides a regenerative output.

New Approach to Power Convertor Circuits

IEE Journal on Electric Power Applications, 1979
The technique of `shorting-coil' switching proposed in this paper provides a novel method of static power conversion. It overcomes the restrictions imposed by the voltage/current ratings of the available power, semiconductor devices and conventional convertor circuit configurations.
