摘要
现代便携式设备通常有锂电池供电和外接电源两种供电方式,锂电池能量密度增加,但系统开销增大,缩短设备工作时间、待机时间和使用寿命。针对该问题,分析了现代便携式设备电源节能方法、管理方法和DC-DC变换器原理与使用方法,提高了便携式设备电源稳定性和适应性,延长便携式设备工作时间、待机时间和使用寿命,实际中得到广泛应用。
Modern portable devices have two kinds of power supply of lithium battery and external power supply. When battery energy density increased, the system spending increased and the working time, wait- ing time and service life shorten. This paper described in detail the modern portable devices power saving method, management method and the DC-DC converter principle and method of use, to improve the stabil- ity and adaptability of power supply for portable equipment, prolong working time, waiting time and service life. It has been used widely in practice.
