C8.4 - Dual-DC/DC Strategy for Enhanced Efficiency in Solar Powered Energy Harvesting

C. Viehweger, T. Pfeifer, T. Keutel & O. Kanoun
Powering autonomous sensor systems with ambient energy sources, called energy harvesting, has become an interesting field of research the last years. Solar based solutions belong to the most developed so far. In electronic systems the voltage of the solar cell must be regulated to match the supplied device, typically 3.3 V or 5 V. It is also necessary to buffer energy to handle peaks in the current demand. These tasks can be fulfilled by different...
