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 ...

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 ...

Recently, I had a conversation with someone who had just moved cross-country to a new apartment. “Got that Windmill hooked up to the window,” she told me, as if she were name-dropping her cable ...

Should you choose a split or window AC for your small bedroom? Compare costs, noise levels, and installation requirements, ...

This application note presents the design guide considerations for a CS1615 and CS1616 single stage, dimmable offline AC/DC controller for LED Lamps. It also present the design process for a single ...

The first time I installed an air conditioning unit—heaving and wedging it with no small effort onto the sill of a fourth-floor bedroom window—I was shocked that more units don’t fall out and plummet ...

The National Electric Safety Code (NESC) includes a clause sometimes referred to as the “5-mA Rule,” which states: For voltages exceeding 98 kV ac to ground, either the clearances shall be increased ...

An engineer asked me for help when he encountered what appeared to be strange phenomenon while testing a prototype circuit in the system. He saw “mysterious” clipping distortion of the signal at the ...
