Batteries aren't one-size-fits-all, and neither is the way they're wired to your house. Here's what you should know about AC- and DC-coupling. When we think about solar panels and batteries, we don't ...

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 ...

Electrical energy is supplied by the grid as AC, yet most devices that we use require DC power, meaning that AC/DC power supplies that make this conversion are one of the most common loads placed on ...

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, ...

Electric vehicles are an important wave of the future, offering motorists a cleaner and more efficient way to travel. But when it comes to charging their batteries, electric vehicles have a particular ...

If you want to convert one voltage to another, what do you do? Well, if you are talking DC voltages today, you’ll probably use a DC to DC converter. Really, these converters generate some sort of AC ...

Significant advances in high-voltage direct current (HVDC) transmission are in step with rapid changes to energy systems worldwide. Shortly after POWER magazine began publication in 1882, the ...

The University of Bath has invested £80,000 in switching its library's network of computers from AC to DC, in the attempt to reduce energy consumption. Later, the system -- which will act as a ...
