Abstract
A device for harvesting electrical energy includes a rectifier and a control device. The rectifier includes a first charging circuit for harvesting energy from a positive voltage of an energy harvester, and a second charging circuit for harvesting energy from a negative voltage of the energy harvester. The charging circuits include a common coil and a common electronic switch. Furthermore, each of the charging circuits includes a capacitor and a blocking element. Because the charging circuits use the coil jointly, the device is designed in a simple and compact manner. In addition, the energy harvesting is efficient, due to the one-stage AC-DC conversion and due to a maximum power point tracking function of the control device.
