Power Density Optimization in High Fidelity Power Drive

IEEE International Conference on Electric Machines and Drives, 2005., 2005
This paper analyzes factors determining power density in high current and high MVA power electronic converters & solid-state switches and recommends practical approaches to increase power density. For years increase in power density was the result of improvements in the power semiconductors density, which is the determining factor in medium power ...

Gearing Design for High Power Density

2020
High 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.

High-Density Avionic Power Supply

IEEE Transactions on Aerospace and Electronic Systems, 1980
Dramatic reductions in size and weight have been achieved in the area of signal and information processing. Power conditioning circuits have not kept pace, primarily due to the relatively slow proggress ress in the passive energy storage and transformation devices.

A high-power-density DC/DC converter for high-power distributed power systems

IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2004
This paper presents a zero-voltage-switching (ZVS) three-level DC/DC resonant converter for high-power distributed power systems. The paper first addresses the operation of the converter at a fixed frequency, which is achieved by applying phase-shift control between the primary and the secondary sides of the transformer.

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.

A high power density high voltage distributed power system for pulse power applications

Twentieth Annual IEEE Applied Power Electronics Conference and Exposition, 2005. APEC 2005., 2005
In this paper, a high-density high-voltage distributed power system for pulse power applications is designed and implemented. Different topologies are evaluated for two power stages. According to pulse load condition, system power density is optimized through the tradeoff between power loss and magnetic component size.

Heat Transfer at High-Power Densities

Journal of Applied Physics, 1953
The power densities that liquid metal cooling is capable of are explored. The advantages of liquid metals over conventional water cooling are shown. The presentation is such that one can choose between the available coolants for any particular application with a minimum of background.

FLOX® Combustion at High Power Density and High Flame Temperatures

Journal of Engineering for Gas Turbines and Power, 2010
In this contribution, an overview of the progress in the design of an enhanced FLOX® burner is given. A fuel flexible burner concept was developed to fulfill the requirements of modern gas turbines: high specific power density, high turbine inlet temperature, and low NOx emissions. The basis for the research work is numerical simulation. With the focus

High Power/Torque-Density Devices

2020
Mechanical power transmission and handling devices are evaluated according to their power density, or else their torque density if it is not the power that is the issue of primary concern. The combination of high power or torque density with good energy efficiency may collectively be termed high-performance density.
