摘要：

A high efficiency piezoelectric energy harvester is designed and experiment results show that the power transformation efficiency of the piezoelectric energy harvester can be enhanced by more than 400% by applying a switching power converter. This switching power converter is derived from Buck-Boost converter, and it is optimized using a control circuitry of low power consumption in this work. The whole circuitry is modeled and simulated in the Pspice software. The simulation results show that the output power of proposed energy harvester increases by 3.4 times after optimization.
