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 ...

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 ...

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 ...

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 ...

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 ...

Make sure you take a look at a new feature on the site, regarding switching-converter topologies for power converters – Flyback transformer enables high power-factor and converter efficiency Several ...

The Forward and Flyback converters are two popular topologies widely used in isolated DC-DC power converters. These topologies are favored by designers for their simplicity, ability to handle multiple ...

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 ...

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 ...
