限制流量特性

在一般的供电系统中,整个电压输出范围内的电流和电压值都是恒定的,而在短路时,输出电压和电流是以折线或直线下降的,这是不理想的。认真考虑负载的所有实际特性可以使系统得到优化。

一个通信电源系统所承受的负荷实际上是许多小负荷的总和。有些负荷具有电阻性,有些通信壳体则具有恒电流,有些则具有恒功率,而且由于充电状态的改变,电池组还会吸入不同的充电电流。若系统以工作于浮充压(包含电池充电电流)的总负载电流来确定其容量,则会剩余大量的供电容量。越来越多的现代通信设备采用了内置的DC/DC转换器,它能提供恒定直流电压,不随通信模块外壳电源输出母线电压的变化而变化。这一恒定功率特性要求母线电压降低时,输入电流增大。若55V负载消耗1A,则40V负载消耗1.3A;而55V负载消耗1A,则40V负载仅消耗0.7A;
