Minimum phase switch-mode boost converter
|500 - Abstract of the offer:|
|The European Space Agency (ESA) has developed a technology that comprises a minimum phase switch-mode boost converter that does not need a floating control. This technology can be used in the electronic equipment industry. A licence agreement collaboration is sought.|
Description of the offer:
The technology offered relates to a minimum phase switch-mode boost DC-DC converter that does not need a floating control. Switch-mode converters have the advantage of being compact while having very high power conversion efficiency.
In this converter, the current is carried towards its output stager when the transistor gate conducts, thus avoiding characteristics of non-minimum phase, and removing zeros from the right half plane.
It has the advantages of a two-inductor boost converter which relate to the continuity of the output current and furthermore, a simple control circuit can be used due to the fact that one of the terminals of the switching device is close to the ground.
Innovations and advantages:
Due to its structure, this converter does not have the disadvantage that the floating control cannot be achieved with an integrated circuit, as it is the case for common converters.
Moreover, having a simpler control circuit may result in lowering the costs of the system.
Commercialisation aspects :
Applications and Markets
The technology may be used in any device that cannot be connected to the electric grid due to mobility or accessibility reasons or autonomous devices. Examples of this are the automotive industry developing hybrid or solar energy powered cars, lighting industry, road signaling industry and power generation industry.
Intellectual property status
Currently patented (France and the USA) and looking for licensing agreements.
