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 ...

High Power Density and High Efficiency of High-Speed Motor
2020 International Conference on Electrical Machines (ICEM), 2020This paper describes the development of highspeed motor with high power density and high efficiency by using the ultra-thin electrical steel sheet in 80μm thick. This steel sheet has a low core loss reduction in high speed motor. These contents are based on the ultra-thin electrical steeleddycurrent loss, The developed high-speed motor is for the Mars ...

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
