摘　　要：在应用了电磁式振动能量收集技术的无线传感器网络节点中,针对半导体芯片在微能量供电的情况下会锁定在一个较低的亚阈值电压使其无法正常工作的问题,文中设计了具有迟滞触发特性的振动能量收集器管理电路。该电路在储能电压达到阈值之前,开关断开,保证存储足够能量。通过Proteus软件对管理电路进行仿真并分析其工作原理。设计管理电路PCB,完成联调测试。实验证明:电路具有明显的迟滞触发性能,静态功耗低,能稳定为无线传感器网络节点提供充足电能。In the wireless sensor network node using electromagnetic vibration energy harvesting technology, in the case of micro-energy power supply, the semiconductor chip will be locked at a lower sub-threshold voltage to make it unable to work normally.Vibration energy harvester management circuit with hysteresis trigger characteristics was designed in this paper.Before the energy storage voltage reached the threshold, the switch was turned off to ensure that sufficient energy was stored.The management circuit was simulated by Proteus software and its working principle was analyzed.The management circuit PCB was designed and the joint debugging test was completed.Experiments show that the circuit has obvious hysteresis trigger performance, low static power consumption, and can stably provide sufficient power for wireless sensor network nodes.
