Several switching-converter topologies exist for power converters that operate from the ac mains and must maintain a power factor of 0.9 or better. One topology is a boost converter with a control ...

For the PDF version of this article, click here. In last month's Power Design column, we examined the functional principles of continuous mode (or incomplete energy transfer mode) of a flyback ...

The HM210-05K060LFTR flyback transformer from TT Electronics is designed for use with Avago's ACPL-32JT/302J IGBT chipset. With its high level of isolation, the transformer is said to be optimised for ...

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 ...

A common part used to create a high voltage is a CRT flyback transformer, having been a ubiquitous junk pile component. So many attempts to use them rely on brute force, with power transistors in ...

[Matt] works at a neon sign power supply company. When a vendor error left him with quite a few defective high voltage transformers, he couldn’t bring himself to ...
