This design was conceived as an add-on for the Variable DC Power Supply, a very successful circuit posted to this website. This simple unit provides a dual-rail variable output ranging from ±2.5V to ...

It’s not entirely clear why [Advanced Tinkering] needs a 50,000-volt power supply, but given the amount of work he put into this one, we’re going to guess it will be something interesting. The stated ...

A double output low noise power supply is an essential tool for any electronics enthusiast. There are many circumstances that a double-output power supply is necessary such as designing pre-amplifiers ...

Adafruit has this week announced the availability of a new adjustable power supply perfect for a wide variety of different projects and applications, enabling you to quickly and easily change the ...

There’s no shortage of cheap & cheerful power supplies which you can obtain from a range of online retailers, but with no listed certification worth anything on them calling them ‘dodgy’ is more of a ...

Power-supply packages will influence the performance, cost, and size of the power supply used in the power-management subsystem. Therefore, the selection process for purchasing a power supply should ...

Fig 1. This efficient pre-regulator for a dc power supply uses an optical feedback loop to minimize dissipation rather than the traditional optically isolated TRIAC drivers. Fig 2. The PSpice ...

‘Double digital’ bench top power supplies use a microprocessor control to lock in key parameters like voltage and current. Not only do these devices include digital LED displays, they also incorporate ...
