【摘要】 采集压电振动的能量是俘获环境能量常用的方式之一。利用压电材料与金属片制成压电振子，在压电振子一端贴上磁铁，利用电机转动驱动压电振子振动。通过磁铁吸合无源磁性开关构成同步开关，运用LTC3588集成芯片，设计了传统桥式整流电路、并联与串联无源同步开关电感电路(SSHI)，并进行了稳压和系统带负载能力测试。所用实验电路与方法为推广SSHI电路的使用提供了参考，实验结果表明，同步开关在压电电压信号峰值闭合，并行SSHI电路的压电能量转移效率要高于串行SSHI电路和传统桥式(SEH)电路压电能量的转移效率。更多还原

【Abstract】 The acquisition of piezoelectric vibration energy is a common way to capture environmental energy.Piezoelectric materials and metal plates are made into piezoelectric oscillators.One end of the piezoelectric vibrator is attached with a magnet,which is driven by the motor to vibrate.Using ltc3588 integrated chip,the traditional bridge rectifier circuit,parallel and series passive synchronous switch inductor circuit (SSHI) are designed and stabilized,and the load capacity of the system is tested.The experimental results show that the piezoelectric energy transfer efficiency of parallel SSHl circuit is higher than that of serial SSHI circuit and that of traditional bridge (SEH) circuit.更多还原
