The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

You use an active-load test circuit to ensure that a power supply for a microprocessor or for other digital loads supplies 100A transient currents. This active load can provide a dc load for a power ...

ATX power-supply designers tend to favor single-switch forward-converter topologies because they are simple and can power multiple, isolated outputs. However, the drawback of these approaches is that ...

Before we go forward and run some of the tests that we are going to see hereinafter, let us check a few of the symptoms to understand if those tests are worth doing. We have mentioned some symptoms ...

Computer power supply units are designed to both power your computer's components and protect them from minor surges. But too large of a surge will blow a PSU's fuse and render a computer powerless, ...

When your bench supply's capacitors are all charged up with nowhere for that charge to go, an active down-programmer is a handy technique that brings rise and fall times back into a viable range. Here ...

There is a great deal of activity in wide bandgap (WBG) power electronics lately, with Gallium Nitride (GaN) and Silicon Carbide (SiC) devices getting a lot of attention due to the technologies’ ...

ActionPower has released a modular programmable ac and dc power supply and load, aimed at testing photovoltaic micro-inverters. Helion, as it will be called, fits a 3U rack slot and designed to work ...
