摘　　要：无线传感器通常长期在野外工作,其电源能耗一直是受业界关注的技术问题。针对采用低压锂电池供电的无线传感器,提出采用多级多路径控制的电源管理方法,实现超低压降、电源超低功耗和大电流输出。采用本电源管理方法的无线传感器不仅能充分利用电池电能量,还能兼容多种供电电源(如锂电池、锂亚电池、干电池、铅酸电池等)的应用场景。Wireless sensors usually work in the field for a long time,whose power consumption has always been a technical problem concerned by the industry.A power supply management metliod based on multi-level mul-tipath control for wireless sensor powered by low voltage lithium battery was proposed,which can achieve ultra-low voltage drop,low power consumption and high current output.The wireless sensor that adopts the power manage-ment method can not only make full use of the battery energy,but also be compatible with a variety of power supply(such as lithium batteries,lithium-thionyl chloride(Li/SOCl batteries,dry batteries,lead-acid batteries,etc.).
