Direct voltage switching converter
|517 - Abstract:|
|The European Space Agency (ESA) has developed a direct voltage switching converter to maximise the power delivered by a space photovoltaic generator. Due to its flexibility, this technology can be used to maximise supplied current by other generators. It can for instance be used within the electronics and the renewable energy industries. License agreement collaboration is sought.|
Description of the offer:
The offer relates a direct voltage switching converter to maximise the power delivered by a space photovoltaic generator. Due to its flexibility, this technology can be used to maximise supplied current by other generators.
The technology comprises a comparator generating a switching signal when an instantaneous value of an output current level is less than a stored maximum value by a preset fraction of the stored value, a diode that reinitialises a peak detector in response to the switching signal and an integrator that generates a control signal switching between an increase state with respect to time and a decrease state with respect to the time in response to the switching signal.
Innovations and advantages of the offer:
The technology makes it possible to obtain a MTTP (maximum power point tracker) system which, while presenting good performance and reliability, is sufficiently simple to enable a plurality of individual generators to be controlled independently, improving the global effectiveness of the photovoltaic generator system and relaxing requirements in terms of isolating and protecting such generators.
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.
