To help power supply development, semiconductor companies offer evaluation boards which show a typical application of a power-management IC. This gives design engineers the opportunity to start their ...

Previously, I posted part 1 and 2 of a 3 part series on how to test your power supply design: measuring efficiency (part 1) and measuring noise (part 2). I covered various noise sources and how to ...

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 ...

The industry’s insatiable need for power in high-performance computing (HPC) is creating problems for test cells, which need to deliver very high currents at very consistent voltage levels through the ...

Recently, the applications in which AC power supplies are used have changed. Until now, because it was mainly used for testing home appliances and office equipment, a high-power capacity of several kW ...

As manufacturers of all types of mechanical equipment work toward using energy efficiently, regenerative power technology has taken a major role in reducing operating costs. Power regeneration is the ...

The electronics industry is seeing a move toward higher voltages and currents to deliver sufficient supply and charging power in products ranging from handheld cellphones and tablets to workstations.

I just received an Enlight 7230 case with 300 watt power supply and am going to build my first system. Any way to check the power supply short of plugging it into motherboard and powering it up? When ...

There are, on occasion, times when we have difficulty testing power supplies. This is often the case when the power supply has an unusual cable for the main motherboard/CPU inputs. Specifically, when ...
