| 摘 要： | 本文以开关电源的损耗为出发点,以回路中的电流为线索,针对AC/DC和DC/DC电路在变换环节所呈现的不同损耗特征指出,有低变高(如24V/48V)的DC/DC方案不经济.本文采用了有无对比原则、成本--效益分析方法,利用等效指标矩阵对拟选方案进行了综合技术经济评价,方法具有一定的创新性.

| Abstract: | This issue introduces a matrixte analyzing chnique to judge of the project using DC/DC power supply to avoid the problem of less room in a site. The key idea in the article is to grasp the clue of the wastage being in switching in power supply. Then we get the result that the project from 24V to 48V is not economy. |
