Abstract
A flipping-capacitor rectifier circuit that enhances an output power of a piezoelectric energy harvester (PEH). The flipping-capacitor rectifier circuit includes a flipping capacitor, a plurality of switches, and an active rectifier. The flipping capacitor is connected in parallel with the PEH and forms at least three reconfiguration phases by turning on one or more of the switches. The active rectifier connects with the flipping capacitor in parallel and rectifies an AC voltage of the PEH. The flipping capacitor flips a voltage across a capacitor of the PEH to enhance the output power of the PEH by extracting power from the capacitor of the PEH.
