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

Development on high-power and high power density capacitor charging power supply
2014 17th International Symposium on Electromagnetic Launch Technology, 2014This paper discussed the high-power and the miniaturization technology of capacitor charging power supply. The design and implementation of parallel operating high power density CCPS prototype with "peak current shifting control" was described. The single CCPS prototype output power is 35kW and the whole output power of parallel operating CCPS is 70kW.

Achieving high energy density and high power density with pseudocapacitive materials
Nature Reviews Materials, 2019Batteries and supercapacitors serve as the basis for electrochemical energy-storage devices. Although both rely on electrochemical processes, their charge-storage mechanisms are dissimilar, giving rise to different energy and power densities. Pseudocapacitive materials store charge through battery-like redox reactions but at fast rates comparable to ...

Power MOSFETs Paralleling Operation for High Power High Density Converters
Conference Record of the 2006 IEEE Industry Applications Conference Forty-First IAS Annual Meeting, 2006In high power high density converters, the power MOSFETs can be used in parallel as the main switch to meet the current rating requirement, increase the switching frequency, and reduce the power loss. This paper investigates the possible benefits and problems associated with the power MOSFETs paralleling operation for higher power high frequency ...

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 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

Gearing Design for High Power Density
2020High power density is one of the major attributes of gearing systems. It could primarily be achieved by adopting designs that feature multiple power paths, which make some of the gears multi-mesh gears, in particular the larger and heavier ones, and some of the pinions double-mesh ones.

A High Power Density Traction Drive
SAE Technical Paper Series, 1979<div class="htmlview paragraph">A new traction drive has been developed which has the power density required for use in both on- and off-highway vehicles. It avoids problems faced by other types of traction drives such as high contact stresses and roller positioning. The range extends from 0 to 1:1.
