Bi-directional DC-DC power converters with high-voltage DC-DC gain

Technology Overview

This technology proposes a novel circuit topology to achieve significantly improved performance when integrated into an EV’s bi-directional DC-DC converter technology or any other application. The design allows for high voltage gain (Step up or Boost) when the converter is supplying energy, i.e., input source (lower DC voltage) to the output (higher DC voltage) load. It is also capable of a high voltage reduction ratio (Stepdown or Buck) when energy is flowing from the higher voltage side source to the lower voltage side load. Seamless transfer from boost to buck mode and vice versa is possible, and this feature is useful for bi-directional power flow such as regenerative breaking. It enables a number of benefits that allow electric vehicles to use several lower voltage batteries in parallel thus improving the reliability.

Novel technique to directly create microstructures on membrane via 3D printing without assembling

Technology Overview

The developed 3D printing-on-membrane in this invention provides a unique way to create complex 3D structures directly on a porous membrane to form assemble-free all-in-one filtration devices. Using the developed technique, different membranes can be structured and functionalized including polymeric or metallic material, with pore size ranging from nanometer to micrometer. The choices of 3D printing ink range from polymer, hydrogel and ceramic. The enhanced and unique attachment between the membrane and 3D-printed spacer/structure through this novel technique creates the potential and opportunity which did not exist before, that is, the ability to have continuity and discontinuity of physico-chemical properties within membrane devices for broad water and energy applications.
