Abstract
An energy harvesting system includes a transducer, a capacitor, a power converter, a power converter control line, a control switch and a control switch control line. The transducer harvests energy and outputs electrical current based on the harvested energy. The capacitor stores a rectified voltage based on the electrical current. The control switch can be open or closed. The control switch control line is arranged to provide a control voltage based on the rectified voltage to the control switch. When the control voltage is equal to or greater than a threshold voltage the control switch is closed such that the power converter control line electrically connects the power converter to a battery in order to provide harvested energy to the battery.
