Power supply design has traditionally placed a high priority on energy efficiency. The system and the end user will pay more if the power supply is inefficient and has non-negligible power losses. Let ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

Resonant-mode topologies offer many benefits over traditional buck, boost, and flyback solutions. These include soft-switching, higher operating frequencies, higher power density, and higher ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

Power gallium-nitride (GaN) FETs have been available for several years now, but some engineers have been slow to adopt them in power equipment despite their superior characteristics. Getting ...

This 16-page guide, “Product focus: power products,” starts with a general introduction to all kinds of devices used in ...

[Hesam Moshiri] has built a variable switch-mode power supply over on hackaday.io. When prototyping a new circuit, often the goal is to get a proof-of-concept working as soon as possible to iron out ...
