Your gadgets run on direct current, but the electricity in your home is alternating current. What’s up with that?

This ac to dc power supply can output 5A in continous operation and 12A peak current. This kind of dc power supplies uses a PCB so you can use two case types for IC1, TO-220 or TO-3. The regulation of ...

This type of power supply seems to be useful to power circuits with low current requirements, on the order of about 1mA to 100mA. Also see : AC line powers microcontroller-based fan-speed regulator ...

When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable pr… ...

Left panel, superconducting rectifier circuit used to convert AC currents into DC using four superconducting diodes (blue) connected by superconducting interconnects and one smoothing capacitor (C ...

In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.

Many large power companies and electrical equipment manufacturers, such as Eaton Corporation, Mitsubishi Electric and ABB Siemens, are rapidly developing DC systems, and the standards needed for ...

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 ...

A specific example would be a UUT (Fig. 1) powered by a 48-V dc source. The UUT typically has a dc current sink with high ac impedance implemented by the UUT’s gyrator circuit.
