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 is a simple circuit used in time of power cut and also used as main power supply. It is a simple circuit used in time of power cut and also used as main power supply. You can also use this circuit ...

The variable step-down MicroModules are suited for point-of-load DC-DC applications, industrial and medical equipment, test and measurement devices, for powering DSPs, FPGAs, MCUs and MPUs, as well as ...

Does it ever just kill you that someone in a factory somewhere got to have all the fun of assembling your bench tools? There are a lot of questionable circuit boards floating around the Internet, and ...

How semi-automated tools speed up the power-supply design process. The five main steps to take when building a power-supply architecture. How do LTpowerPlanner and LTspice help facilitate the ...

In the design of power supplies, the desired output voltages can be set manually. This is accomplished in most integrated power supply circuits, as well as switching and linear regulator ICs, with the ...

Noise is a constant problem in power-supply design. While there are FCC limits on the electromagnetic interference (EMI) radiating out into the air as well as the conducted noise that your design ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

Article 725 provides the requirements for Class 1 circuits in Part II. A Class 1 circuit is that portion of the wiring between the overcurrent protective device (OCPD) of a Class 1 power supply and ...
