When developing TOPSwitch flyback power supplies, transformer design is usually the biggest stumbling block. Flyback transformers are not designed or used like normal transformers. Energy is stored in ...

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 ...

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. Let's return to the question, “Why Have an Air Gap?” initially posed in the Power Design article in the December 2002 issue of Power Electronics ...

[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 ...

In PoE systems, performance of the flyback converter used to step down the 48-V supply in the powered device depends on careful transformer design. A growing number of electronic devices require both ...
