An ORNL invention proposes using 3D printing to make conductors with space-filling thin-wall cross sections. Space-filling thin-wall profiles will maximize the conductor volume while restricting the path for eddy currents induction.
A Family of Integrated On-board Charger for Single and Dual Motor based Electric Vehicle Power Train
The invention aims to reduce the cost, weight and volume of existing on-board electric vehicle chargers by integrating power electronic converters of the chargers with the traction inverter.
The traditional window installation process involves many steps. These are becoming even more complex with newer construction requirements such as installation of windows over exterior continuous insulation walls.
New demands in electric vehicles have resulted in design changes for the power electronic components such as the capacitor to incur lower volume, higher operating temperatures, and dielectric properties (high dielectric permittivity and high electrical breakdown strengths).
A new, simpler power module and manifold design shows lower weight and volume, which allows higher power density compared with current state of the art.
Wind or hydro power are predominantly large-scale with giant generators to convert wind or water captured by turbines into electricity. But residential-sized wind turbines could generate power for a whole house.
There is a strong drive to improve the electrical performance of a power module for power electronics applications including transportation, buildings, renewables, and power delivery.
Wireless charging systems need to operate at high frequency, at or near resonance, to maximize power transfer distance and efficiency. High voltages appear across the inductors and capacitors. The use of discrete components reduces efficiency, increases system complexity.
The interface gasket for building envelope is designed to enhance the installation of windows and other objects into building openings.
ORNL has developed a revolutionary system for wirelessly transferring power to electric vehicles and energy storage systems, enabling efficient, contactless charging.
