摘　　要：针对能量回馈型超声波电机既具有精密驱动功能,又具有振动能量采集功能的要求,设计了基于TMS320LF2407的能量回馈型超声波电机驱动与能量采集电路,分析了电路的各个组成模块,并对电路硬件进行了设计与仿真;研制了电路硬件系统,搭建了电路测试平台,对电路进行了测试分析。研究结果表明:设计的驱动电路能够满足超声波电机的驱动要求,能量采集电路具有较好的采集回收功能,为在能量供应不足的场合实现超声波电机的持续应用提供了一种可行的解决方案。In order to match the demands of precision actuating and energy harvesting functions of the energy harvesting type ultrasonic motor,a driving circuit and an energy harvesting circuit were designed based on the TMS320LF2407 in this paper. The components of the whole circuit were introduced and designed,some simulations were carried out to analyze the circuit performance,and the experimental setup was established to test the whole circuit. The research results show that the driving circuit can math the driving demands of the ultrasonic motor. The energy harvesting circuit has a high efficiency to convert vibration energy into electric energy. The driving circuit is contributed to solve the energy shortage in the occasion of the ultrasonic motor applied.
