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 ...

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, ...

But what do these three quantities really mean? A full explanation would take a whole semester, so let me instead give a brief summary. The ΔV is the change in voltage (also sometimes just called ...

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 ...

You can't avoid power line disturbances altogether, but you do have access to options for mitigating voltage, current, and frequency deviations produced by the electric utility system. You can ...

Most AC-DC power supplies and DC-DC converters have internal current-limiting circuits to protect the power device, and to some degree its load. The majority of over-current-protections include an ...

High-voltage direct current (HVDC) technology offers several advantages compared to alternating current transmission systems. For example, it allows more efficient bulk power transfer over long ...

Nowadays, chip vendors are devoted to developing new power savingtechniques in order to extend the battery life of portable devices suchas cell phone, MP3 player, portable media player, notebook PC, ...

Have you ever wondered whether your USB ports are really delivering maximum power? There are several ways to find out. Windows offers you built-in functions to check the performance of your USB ports.

High-voltage power transmission systems are more important today than ever before because power generated at renewable energy sites in remote locations must often be transmitted to distant load ...
