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 ...

The R&S NGT3600 series delivers up to 1800 W per channel, dual-channel flexibility, ultra-low ripple, and precise ...

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 ...

A variable dc power supply is one of the most useful tools on the electronics hobbyist’s workbench. This circuit is not an absolute novelty, but it is simple, reliable, “rugged” and short-proof, ...

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 ...
