For one-off projects or prototyping, it’s not too hard to find a wall wart or power supply to send a few joules of energy from the wall outlet to your circuit. Most of these power supplies use a ...

In some power-supply applications, the pulse-width-modulator (PWM) controller is powered up from an auxiliary winding tapped off the power stages transformer (Fig. 1). This technique reduces power ...

My two file servers have redundant power supplies with all ps's plugged into a UPS. The UPS's are on the same circuit. I want to plug one ps/UPS from each server into another circuit for an additional ...

A power supply for electronic devices. Also called an "AC adapter" or "charger," power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and ...

Modern integrated circuits are increasingly vulnerable to power supply noise and the ensuing induced jitter, phenomena that can significantly impair circuit reliability and performance. The interplay ...

In the last decade or so, significant advances have been made in the design of industrial power supplies and dc-dc converters, from the materials and device levels to size and weight reduction, ...
