TDK Corporation announces the TDK-Lambda brand EVS constant current AC-DC power supplies. The board style 300W rated models can operate without forced air cooling, with the enclosed 600W models having ...

The purpose of this project is to control the current across a load by using pulse width modulation for maximum power efficiency while being constructed on a breadboard. The project accommodates the ...

Every automated test system that tests electronic circuit boards, modules or equipment needs one or more DC power supplies. Specifying the right supply involves more than just finding one that can ...

Here is a nice hack you may find very useful if you have a cheaper bench power supply that supports constant current limit protection (CC mode) and the only way to set or check your max current limit ...

Different components affect system accuracy. Shaury Anand, of Texas Instruments, explains how to choose those most suitable for a precision DC power supply design. Test and measurement applications ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...

Improving the efficiency of a power-supply design can yield many rewards. In a server farm, better efficiency translates into smaller size, reduced cooling costs, and a lower electricity bill. In a ...

Most AC-DC power supplies and DC-DC converters have internal current-limiting circuits to protect the power device, and to some degree its load. The majority of over-current-protections include an ...

Direct current (DC) power supplies refer to an embedded circuit that provides constant and stabilized power supply to electronic modules. They are commonly available in two forms, namely switching and ...
