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 ...

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 ...

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 ...

From our discussion in last month's Power Design column, we know that low cost and simplicity are the major advantages of the flyback topology. In multiple output applications, the addition of a ...

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 ...

The pulse-edge transformer (PET) is used as a medium to transmit PWM pulses from a secondary-side controller, such as EZ-PD™ PAGxS, to a primary-side controller, such as EZ-PD™ PAGxP, for AC/DC ...

LEDs have come a very long way in performance and “comfort factor” in the past few decades for many good reasons. At the same time, the basic ac-line LED “supply” consisting of an ac/dc voltage-output ...

This course covers the analysis and design of magnetic components, including inductors and transformers, used in power electronic converters. This course assumes prior completion of ECEA 5700: ...

[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 ...
