摘要
在设计电源过程中为了达到系统所要求的电流,作者通过对几种扩流电路的对比研究与实验,总结了几种较为理想的线性分压扩流方式—电阻分压扩流与三极管分压扩流。这些扩流电路扩流效果明显,电路结构简单,成本低廉,非常适合对电源转化效率要求不是很高的场合。
In order to achieve the right current demands when designing a power-system,the author made a comparing study and practice among several linear current expansion circuits and got some useful circuits from them which are divided voltage by resistance and transistor in order to expand current.The effects of the current expansion circuits are obvious,and they have a simple structure,and cost low.Specially,these circuits are very useful to some occasions that the conversion efficiency of power is not very high.
