To improve efficiency in high-power applications, voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach ...

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 ...

An electric current is a flow of charged particles. A source of energy, such as a cell or battery, is required to make the free electrons move in one direction. Electrons are negatively charged ...

Modern energy use is becoming more flexible. People no longer need batteries only for cars, flashlights, or small backup ...

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 ...

There are two main types of electrical current that flow through your home: Alternating and direct. The vast majority of devices around you are powered by alternating current. By allowing electrons to ...

Every single desktop PC, console, or laptop has one of these. It won't boost your frame rate, nor does it have billions of transistors, and it's not manufactured using the latest chip process nodes.
