Abstract
A method of operating a vibrational energy harvesting system includes providing an energy harvester and an energy storage module. The energy storage module is coupled to the energy harvester to transfer energy to the energy storage module. The method also includes determining whether the energy transferred exceeds a predetermined threshold. The method further includes limiting the energy transferred to the energy storage module by a passive device when the energy transferred exceeds the predetermined threshold.
