I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using th… ...

Variable regulated power supplies are handy tools found on well-equipped electronics lab benches. The symmetrical varieties that produce equal voltage outputs of opposite polarity, are even more so.

A new fully featured Arduino development board has been created called the Prestissimo Uno+ which is now available to back via Kickstarter with earlybird pledges available from just $20, AUS$28 or ...

Intersil Corporation announced the ZL8801 dual-phase, DC/DC digital PWM controller. The ZL8801 dual-phase, DC/DC digital PWM controller from Intersil Corp. expands Intersil's fourth generation ...

Lian Li introduced the EDGE GOLD series power supply units (PSUs) as the latest extension of its T-shaped PSU lineup. Designed specifically for dual-chamber and tower cases, the EDGE GOLD series ...

The upgraded version of Power Supply Designer software now provides a library with over 14,000 SPICE models, including PWM ICs, IGBTs, power MOSFETs, and transformers. This integrated ...

The machine uses a ‘grbl’ controller, which has an Arduino-based circuit that includes multiple outputs, including a powerful 24V pwm signal that is generally used to drive a 60-80W spindle motor..
