Most people have a phone charger plugged in next to their bed, which they never bother to switch off at the wall - but is that risky to do?

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 ...

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 ...

Researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) are breaking technical barriers with faster circuit breakers to enable and protect the modern electric grid. The ORNL ...
