Assessment of the free-piston Stirling convertor as a long life power convertor for space [PDF]

open access: yesCollection of Technical Papers. 35th Intersociety Energy Conversion Engineering Conference and Exhibit (IECEC) (Cat. No.00CH37022), 2000
There is currently a renewed interest in the use of free-piston Stirling power convertors for space power applications. More specifically, the Stirling convertor is being developed to be part of the Stirling Radioisotope Power System to supply electric power to spacecraft for NASA deep space science missions. The current development effort involves the

Non‐isolated high step‐up DC–DC converter based on switched‐inductor switched‐capacitor network for photovoltaic application

open access: yesIET Generation, Transmission & Distribution, 2023
A high step‐up non‐isolated DC–DC converter based on a switched‐inductor/switched‐capacitor network is proposed in this paper. The proposed converter takes advantage of both active and passive switched inductor cells. Inductors L1 and L2 can be connected

Formulation of the energy-storage factor for isolated power convertors using integrated magnetics

open access: yes, 2005
The energy storage in energy-storage components is examined for isolated power convertors. In addition to the basic convertors such as the flyback and forward, the paper also develops the analysis for the various isolated versions of power convertors as ...

Harmonic modelling of transmission systems containing synchronous machines and static convertors [PDF]

open access: yes, 1985
This thesis describes the modelling of the major sources of harmonic distortion in electrical transmission systems, especially those of relevance to the New Zealand power system. The harmonics generated by the operation of a.c./d.c.

ENHANCING STABILITY AND REGULATION OF OUTPUT VOLTAGE IN BOOST CONVERTERS WITH LEARNING SLIDING MODE CONTROL

open access: yesMağallaẗ Al-kūfaẗ Al-handasiyyaẗ
Although DC to DC convertors might be considered as the most widely used circuits in power electronic, where a specific DC output voltage must be stabilized to a specific desired level, yet theses circuits unfortunately exhibit a nonlinear behavior.

Multipulse improved-power-quality AC–DC convertors for vector-controlled induction-motor drives

open access: yes, 2006
The paper deals with polygon autotransformer-based 12-pulse and 18-pulse AC-DC convertors feeding vector-controlled induction-motor drives (VCIMDs) for improving power quality at the point of common coupling (PCC).

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
