Last week, I posted part 1 of a 3 part series on how to test your power supply design: Testing power supply: measuring efficiency. I covered the fundamentals about testing, including the necessary ...

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 ...

Your PC’s power supply is one of its most crucial components, but most people barely ever give it a second thought once it’s installed. And that’s kind of weird ...

Recently I built a computer for my girlfriend's uncle. He was having problems with it from the start, namely that the computer would reboot or give him problems if he shut it off. (Not shut down. Shut ...

Testing a power supply at different load currents and different input voltages is important, but it only shows part of the truth. A Bode plot can reveal the rest. The importance of using a Bode plot ...

If a building has an electrical generator for power outages, one of the most valuable commissioning tests will be the loss of power response (LOPR) test, also known as a pull-the-plug test. This is ...

The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. In this ...

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 ...

Ever since manufacturers of electronic equipment, devices, and instruments mastered the production of safe and reliable products, they’ve been constantly pushing for increased efficiency. The demand ...
