摘要： An apparatus and method for tracking maximum power are disclosed. The apparatus is configured to track a maximum power at a certain node of an electronic circuit, adjust an impedance of the electronic circuit such that power at the node is maximal, and adjust an impedance of the electronic circuit by comparing power at two points in time to increase power. The apparatus for tracking a maximum power, includes a charge sharing capacitor connected to an initial capacitor in parallel, a first switch disposed between the initial capacitor and an energy harvesting power supply, a second switch disposed between the initial capacitor and the charge sharing capacitor, a third switch disposed between the energy harvesting power supply and a comparator, and a switched-capacitor power converting circuit configured to control the initial capacitor.
