Abstract
An energy harvesting system includes a plurality of energy converters connected to multiple ambient energy sources, respectively, receiving energy from the multiple ambient energy sources, and converting the received energy into electrical energy. The system also includes an electrical energy buffer receiving and collecting electrical energy from the energy converters, and combining the collected electrical energy to have a predetermined power level and a constant voltage converter receiving the combined electrical energy from the electrical energy buffer, and converting the received electrical energy into driving power of a power level usable by a load. The system further includes an electrical energy storage receiving the driving power from the constant voltage converter, storing the received driving power, and providing the stored driving power to the load. When internal power is generated in a specific energy converter, the generated internal power is selectively used as external power for another energy converter.
