Abstract
More and more piezoelectric power generators are used in the field of energy harvesting in recent years, which are the typical capacitive power sources. The piezoelectric power generator is difficult to achieve maximum power output when it works in a low-frequency energy harvesting system. A frequency conversion management circuit is proposed in this paper, which can achieve the conjugate impedance matching between the power generator and the management circuit. The experiment result shows that the frequency conversion management circuit can obtained 411% more energy compared with traditional management circuit.
