摘　　要：为了提高涡激式微型风能采集装置能量回收功率,文章基于同步电荷提取(SECE)电路,利用MSP430超低功耗单片机系统,设计了硬件电路与控制算法。对压电双晶片的两端电压进行峰值检测,同时产生脉冲信号,控制电路中MOS管的导通与关断,缩短压电片积累电荷的能量损耗,提升电路的回收功率。实验结果表明,在风速为14,16 m/s和18 m/s的条件下,与经典电路相比,基于SECE电路的涡激式微型风能采集装置的能量回收功率分别提高了75.3%,52.2%和47.8%。In order to improve the efficiency of micro wind power collection by vortex-induced vibration,a Synchronous Electric Charge Extraction(SECE)circuit is developed with MSP430 single chip microcomputer.The hardware circuit and control algorithm is designed to detect the voltage peak and generate the pulse signal which can control the on/off state of MOSFET.Because the energy loss during the charge accumulation of piezoelectric patch is reduced by the propose energy interface circuit,the efficiency harvested energy of micro wind power can by improved.Experimental results show that comparing with the standard interface circuit,the harvested power with proposed SECE energy interface circuit is increased by 75.3%,52.2%and 47.8%in the wind speed of 14 m/s,16 m/s and 18 m/s.
