你有没有想过，家里的手机充电器、笔记本电源，为什么能把墙上 220V 的交流电变成设备需要的 5V、3.3V 直流电？今天就带大家深入了解 AC-DC 的奥秘，从转换原理到 PCB 设计，干货满满！ 为什么非要 AC 转 DC？ 日常电器如手机、路由器等，大多需要 5V、3.3V 的直流 ...

When choosing a switch to use in an electrical design project, there is a perception that it is possible to use any switch, provided its current rating is greater than the maximum load in the circuit.

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

Part 2 provides an analysis of the factors that affect energy savings. Various types of DC power distribution are examined as alternatives to AC distribution for data centers and network rooms. A ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...
