Abstract: This paper studied on several magnetic energy harvesting circuits based on piezoelectric effect. Introduction was made to the structure and working principle of different energy management circuits. The output power characteristics of each energy management circuit were carried out simulation by MATLAB when the piezoelectric material was subjected to the force of constant amplitude. A magnetic energy harvesting device of cantilever beam structure and several circuits were designed to measure the output power characteristics of various energy management circuits under the power frequency magnetic field of constant amplitude. The results show that the output power can be increased by 13.14% under 2.4 Oe power frequency magnetic field by using the S-SSHI circuit. Magnetic field energy can be successfully collected near 20 A current-carrying conductor with this device.
Key words: magnetic energy harvesting; energy management circuit; piezoelectric effect; steady magnetic field
