摘要：
为给输电线路上低功耗在线监测设备提供稳定可靠的供电，设计一种多能量供电电源，可利用磁场能、太阳能与锂电池实现混合能量管理方案。通过理论分析、有限元仿真分析、硬件电路设计、实验平台的搭建证明该电源良好的应用效果。实验表明，该电路能够给负载提供3.3 V不间断的供电电压；当两种环境能量都没有输入时，仅锂电池就可为平均消耗500 mW的负载供电73.92 h，满足为负载稳定持续供电的要求，增强了供电稳定性，提高了能源的利用率，能有效延长锂电池的使用寿命。同时，对多能量供电系统的推广和应用提供了参考价值。

Abstract: In order to provide stable and reliable power supply for low-power online monitoring device on transmission lines, a multi-energy power supply is designed, which can realize hybrid energy management by using magnetic field energy, solar energy and lithium battery. Through theoretical analysis, finite element simulation analysis, hardware circuit design and experimental platform, the good application effect of the power supply is proved. Experiments show that the circuit can provide 3.3 V uninterrupted power supply voltage to the load; when there is no input of two kinds of environmental energy, only the lithium battery can supply the load with an average consumption of 500 mW for 73.92 hours, which meets the requirement of stable and continuous power supply for the load , enhance the stability of power supply, improve the utilization rate of energy, can effectively prolong the service life of lithium batteries. Moreover, it provides reference value for the promotion and application of multi-energy power supply system.
