BOOTSTRAPPED CHARGER

摘要

The invention provides methods and systems (100, 200, 300, 400) for energy harvesting in which an energy storage device (12, 28, 39) is connected to a charger (14, 24, 30, 48) having a charge controller (17, 22, 46). In turn, a bootstrap circuit (11, 21, 33, 41) connected to the charge controller (17, 22, 46) provides power sufficient to cause the charge controller (17, 22, 46) to supply current to the energy storage device (12, 28, 39). Subsequently, the charger (14, 24, 30, 48) is used to regulate the output of a plurality of energy harvesting devices (10, 29, 33, 34, 44) operably coupled to the charger (14, 24, 30, 48) and to the energy storage device (12, 28, 39).
