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 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 ...
