Contract associated with the europpean project "EARTH": Energy Aware Radio and neTwork tecHnologies. The goal of the project is to reduce by 50% energy consumption of base station.
The work was based on DC-DC converter. Some realisation has been made for the system special requirement. The particularity of the DC-DC was his adaptability and the speed of this adaptability.
- Studies and state of the art in publications and competitor. Work on architectures, automatic control, design, components.
- Design, realization, test and characterization of innovative DC-DC converter for 4G Macro-Cell Base Station.
- Realized DC-DC converter modelling to enhance speed transition.
- Efciency measurement.
