电源供应

台湾现用之美规UL-NEMA 5-15插头与插座(俗称“H型接地”,但此俗名与 IEC 国际标准所称“以色列使用的 Type H”会混淆)
中国大陆插座:图左为较少见的16安培三脚插座,一般用于空调、热水器;图右为较常见能接受“不接地 A型或 C型插头混合”及“接地 I型插头”的双插座(图右下接地 I型插头为常见的10安培三脚插座)

电源供应(英语:power supply)又称电力供应,通常是指提供电子设备(如服务器电脑等)有功功率的电子装置,即电源供应器;也指电源(power source)或供电

电源供应器的主要功能是:将来源电力转换成电子设备可以使用的电压、电流、频率以使电子设备可以正常运作,因此电源供应器有时被视为电力转换器(electric power converter)。有些电源供应器是分离于电子设备独立装置,有些则是内建于电子设备中;如电脑和一些消费性电子设备都有内建电源供应器。电源供应器的另一个重要功能是:将电流因负载的消秏控制在一个安全范围内,在电子设备发生故障时关闭电流。

所有的电源供应器都有电力“输入连结端”,可接收来自来源电力的电流;而且有一个或多个“输出连结端”,以传送电流至所需的设备或零件。

电力供应

发电机

电力供应包括配电系统,以及中小型的能源供应,例如:

对于大型的电源供应,详见发电

电源供应的类型

可编程电源供应器

过载保护

电源的供应通常包括某种类型的过载保护,保护电源与预防负载故障所造成的短路,避免因为过热造成火灾

供电量

供电量指在供电生产过程中投入的全部的电量,计算供电量的公式为:

地区供电量=本地区电压上网电量+输入电量-输出电量。
