Abstract:
"Latest wearables and IoT sensors use intelligent nano-power circuits and devices that harvest energy from environmental sources such as light or heat. Historically, there has been a gap between the energy demands of these circuits and the energy available from harvesting sources. Presently, we are approaching the cross-point where available harvested energy can exceed the energy consumption, making energy-autonomous systems possible. One significant problem is that energy harvesters such as thermoelectric generators typically produce a very low voltage. The available harvested energy is thus unusable without a power management integrated circuit to provide high efficiency voltage conversion at very low source voltages. This presentation includes fundamental research on existing solutions, the scientific value of a new boost converter topology and a summary of the results and shows first applications."
This presentation was recorded as part of the lecture "Selected Topics of Advanced Analog Chip Design" from the Institute of Electronics at TU Graz.
Special thanks to Dr. Christoph Steffan, for the insightful presentation.
