Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

Voltage optimisation (VO) is just one element of a broader power quality strategy, and understanding its limits and ...

Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the necessity for special electronic loads, ...

This article is adapted from a presentation at TestConX, March 5-8, 2023, Mesa, AZ. A power-delivery network (PDN), also called a power-distribution network, is a localized network that delivers power ...

Power supply manufacturers sometimes hear from customers with unfortunate dilemmas, such as, “I need to operate the power supply outside its rated voltage range.” Or, “What happens if I exceed my ...

If you turned the page, saw the pictures, and had a mild panic, don't. Sure, we're going to be dealing with electricity, or more specifically the current draw of the various electrical systems in your ...

Inevitably, industrial facilities are going to have 460VAC, 3-phase motor loads. And, of course, since voltage drop is considered mainly a performance issue, maximum voltage drop rules on a circuit ...

Two Solarlytics units installed next to a DC combiner. DC-DC converters are one option for tackling the issue of voltage collapse. Image: Solarlytics. As solar plants age and face varying ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...
