ROHM leverages its LogiCoA technology to control a power-factor-correction stage and flyback DC-DC converter stage at the same time.

Measurement accuracy depends on the DC power supply’s accuracy specifications, how the power supply monitors its output, and how it’s wired to the device being tested.

When designing an isolated power supply for PMDC motors, several considerations influence the design of the power-converter topologies.

This time, he reviews and tears down the Topshak LW-3010EC programmable DC power supply, first putting the unit through its paces, then opens it up to see how it looks on the inside.

A lot of recent quality power supplies are built as a big 12V PSU, with the minor rails being supplied via DC-DC converters powered by the PSU's 12V output, instead of the old group regulated ...

Understanding the important formulae involved in selecting a DC motor coil will help engineers and designers understand how power supplies impact coil selection in various scenarios.

Batteries are a part of our everyday life, and power everything from phones to gaming handhelds to laptops, but do those batteries use AC or DC current?

So let's say our DC power supply runs at 10 volts. We can use this to find the level of resistance needed to get our toast nice and toasty.

Modular programmable power supply tests PV inverters ActionPower has released a modular programmable ac and dc power supply and load, aimed at testing photovoltaic micro-inverters. Helion, as it will ...
