In the 1990s, experts calculated that without efforts to increase efficiencies and reduce “no-load” power consumption, external power supplies—the ones used to power everything from cell-phones to ...

No electricity provider in the world can guarantee an electrical supply that is free from voltage and frequency variations. The possibility of faults occurring in user installations or in the public ...

Regardless of the system architecture, the circuit design, or the power levels involved, transient load current step testing is a critical aspect of power-system design, test, and verification.

Over the years, the need for increased reliability of electrical systems is no secret to those in the electrical industry. Data centers, hospitals, emergency call centers, government buildings, and ...

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

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 ...

In parts one and two, I made a case for the idea that real power handling was intimately tied to the nature of the signal, as well as the electromechanical parameters of the speaker under test. We ...

It’s taken almost 10 years to design and construct, but researchers at the U.S. Department of Energy’s Idaho National Laboratory have now energized and put into service one of the nation’s most ...
