The harnessing of electricity has played a pivotal role in human history and has exponentially expedited our growth as a species. Since becoming a household commodity in the late 19th century, ...

Significant complications arise when trying to get your power supply working from a wall outlet. Making a dc voltage from an ac source means you will have to rectify the ac voltage to get a dc bus.

When energy-efficiency costs come into play, more designers are opting for the electronically commutated motor rather than familiar AC and DC versions. For motor applications, engineers have several ...

Calculations of power and energy are relatively straightforward when the subject is strictly dc circuits. The situation is more complex in the ac world, however. Here are the basics of watts and ...

As the story goes, the rock band AC/DC took its name from a label on an old sewing machine in the Young brothers’ home. It must have meant that the machine could run on either alternating-current or ...

While seemingly mundane, wall phone chargers — whether that's a GaN phone charger, fast charger, or just the regular USB-A charger — have become a necessary staple in your daily routine. You need it ...

When picking a switch to use in electrical design, many people believe they can use any switch, provided its current rating is more than the maximum load in the circuit. This, of course, isn’t true.

High-voltage direct current (HVDC) technology offers several advantages compared to alternating current transmission systems. For example, it allows more efficient bulk power transfer over long ...

The AC/DC power supply, commonly referred to as an AC/DC converter, is a vital element in several electronic applications, including consumer electronics, industrial, robotics, medical, and military ...
