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 ...

In an effort to meet worldwide efficiency requirements, engineersare designing offline power supplies integrating high-efficiencyswitching-regulator-control circuits. This approachuses less copper and ...

The elephant in the room has a name: Axl Rose. AC/DC singer Brian Johnson’s actual room is illuminated by standing lamps on either side of a long, dark couch; he perches in the middle with his ...

A digitally controlled ac/dc switching power supply can be programmed for specific parameters. A new line of switching power supplies features advanced digital management capabilities. The iMP series ...

Switches seem to be the simplest of electrical components – just two pieces of metal that can be positioned to either touch each other or not. As such it would seem that it shouldn’t matter whether a ...

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.

For switching high-powered loads from a microcontroller, or for switching AC loads in general, most of us will reach into the ...

A primary-based CC/CV design slashes parts count to achieve cost parity with 3- to 4-W linear power supplies. Over the past few decades, switching power supplies have become an increasingly popular ...
