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 ...

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.

Consumer electronics, industrial, robotics, medical, and military applications all frequently use an AC/DC power supply, also referred to as AC/DC converter. An accurate design of the power supply ...

The demand for smaller, lighter, and more efficient AC/DC USB power delivery (PD) chargers is always a challenge for power-supply design engineers. Below 100 W, the quasi-resonant flyback is still the ...

Advancements in power TVS diodes have made them an effective alternative to metal oxide varistors (MOVs) in protecting AC and DC power supplies from power line surges and indirect lightning strikes.

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...
