资料介绍

为了实现高效率地收集环境中的各种微弱能量,设计了一种低功耗的微弱能量收集电路。采用LTC3588-1电源管理芯片为核心的电压变换电路、LTC4071充电控制芯片为核心的充电控制电路、TPL5100为核心的定时器电路搭建低功耗微弱能量收集电路,设计的电路能够将收集到的微弱能量转换为电能存储到锂电池或者提供给负载供电。实验结果表明,设计的低功耗微弱能量收集电路实现了微弱能量的收集,能量收集电路自身平均功耗低至182μW,验证了收集微弱能量给无线传感器网络节点供能的可行性,电路因低功耗、低成本等优点,具有应用前景。

In order to achieve the high efficiency of harvesting various ultra-low energy in the environment,a low-power circuit for ultra-low energy harvesting was designed.Using a voltage convert circuit which is mainly supported by power management chip LTC3588-1,a charging control circuit whose core is charging control chip LTC4071 and a ultra-low harvest circuit which is de-signed by timer circuit TPL5100,the circuit could storing the energy harvested to lithium battery or supplying power to load.According to the experimental result,the circuit can be used to harvesting the ultra-low energy and the average power consumption of the circuit is low to 182 uw,which verifies the feasibility of ...
