A high power density VHSIC power supply
Fifth Annual Proceedings on Applied Power Electronics Conference and Exposition, 1990A regulated 3.3 V, 10 A supply that combines several innovative approaches is described. The power stage is based on the Cuk converter which allows a very effective application of the integrated-magnetics technique: all magnetic elements (input and output filtering inductors, transformer) are combined on a single magnetic core resulting in a very ...

Abstract In the context of new generation rare isotope beam facilities based on high-power heavy-ion accelerators and in-flight separation of the reaction products, the design of the rare isotope production targets is a major challenge. In order to provide high-purity beams for science, high resolution is required in the rare isotope separation. This

High-Power-Density Superconducting Generator
Journal of Energy, 1982The application of superconductors to the field windings of synchronous ac generators has been the subject of considerable development effort over the past decade. Machines and/or components have been built and tested in more than half a dozen countries. This paper considers an airborne high-power-density superconducting generator under construction at

Thermoacoustics at high power density
The Journal of the Acoustical Society of America, 1996Some applications of thermoacoustics will require high power density to reduce the cost and size of the hardware needed for a given total power. Such high power density can be reached by using high acoustic amplitudes, but this leads to significant differences between the actual operation and predictions based on the acoustic approximation.

High Power-Density SiC Converter
Materials Science Forum, 2008A compact SiC converter having power densities about 9 W/cm3 is designed and fabricated. It is confirmed that the converter operates in a thermally permissive range. The power loss of the module of the converter measured under motor operations is less than 50% of the similar-rating Si module loss. The shrink of the effective volume of DC-link capacitor

Piezoelectric polymers are characterized by their flexibility and ease of processing into shapes, however, their piezoelectric coefficients, such as d33, are quite low (∼24 pC N−1). Here we report a 3D-printed multilayer β-phase PVDF-TrFE copolymer which

High power density thin film resistors
1975 EIC 12th Electrical/Electronics Insulation Conference, 1975Untrimmed Ni-Cr resistors on glazed alumina substrates, hermetically sealed in a dry nitrogen atmosphere, survive and remain stable when subjected to power densities greater 2000 W/in2. Large (>7 × 10−4in 2 ) resistors with standard top-hat trimming fail at less than 1000 W/in2 due to hot spots, however, a change in trim line configuration results in ...

High Power Density Design Methodology
2007 Power Conversion Conference - Nagoya, 2007Power Electronics Research Center (PERC) proposes a novel circuit parameter design concept called "Power Converter Design Platform" for realizing high output power density (OPD) converters. The platform concept enables the exact power loss design by taking the effect of correlations among converter parameters into consideration under high speed ...
