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.

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 ...

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 ...

An electrical contractor in Austin, TX, posted a super-informative blog post about understanding AC and DC electrical currents. This is what the differences boil down to: "DC" means "direct current".

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 ...

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 ...
