The invention relates to electric machines and more specifically to an uncluttered flux coupling machine for replacing doubly fed brush in wind turbine generators. The conventional doubly fed, brush-type, rotating-inverter generator can be replaced by this technology.
A power transmission system includes a loosely coupled air core transformer having a resonance frequency determined by a product of inductance and capacitance of a primary circuit including a primary coil. A secondary circuit is configured to have a substantially same pr
The present invention provides a method to greatly extend the lifetime of nickel superalloy components employed in high temperature thermally-based electricity generation.
There is an urgent need for new electrochemical cell chemistries to achieve increased electrical energy storage capacity and rate capability for future energy storage needs, yet few viable new cathode materials have emerged.
HVAC energy efficiency is important because HVAC systems are essential, and their cost of operation is continuous. Effective methods for increasing HVAC efficiency can greatly impact the overall cost of operation.
The invention relates to reduced power consumption and more specifically to a new technique for radio data transmission that will significantly reduce the power requirements for operating the radio.
High power and high energy density are essential to batteries for applications in electric vehicles, stationary energy storage systems for solar and wind energy as well as smart grids.
Electrical energy storage systems have attracted significant attention within the past few decades due to the sustained interest in alternative energy sources which stems from the gradual depletion of oil resources around the world.
During the last three decades, a large variety of materials have been synthesized and evaluated as cathode materials for Li-batteries.
We designed and synthesized a titanium dioxide material with novel architecture, which combines the features of the TiO2–B polymorph with mesoporous structure and microsphere morphology.
