ABSTRACT:
An energy harvesting system and method having improved efficiency. A primary energy harvesting device is used to generate a first electrical output signal. The first electrical output signal is applied to a first switching circuit. A secondary energy harvesting device is used to generate a second electrical output signal that is used to power a second switching circuit. The second switching circuit generates the switching drive signal for the first switching circuit, which in turn generates a final output signal. By using a second energy harvesting circuit operating in connection with a different structure, and a secondary switching circuit, less power from the signal generated by the primary energy harvesting device is needed to power the first switching circuit. This results in a greater percentage of the output power of the first signal being usable by an external device.
