A power transformer technology developed by Plitron Manufacturing Inc. of Toronto, Ontario, attenuates differential and common-mode noises on the ac mains to the extent that external filtering may be ...

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 ...

The flyback design is a switched-mode power supply (SMPS) that’s been used for 70+ years and still going strong. This supply—also called a power converter—has two distinct operating phases, with power ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

When designing an offline flyback power supply, integrating the IC with the other components can be overwhelming. Integrating the transformer properly is more than finding the turns-ratio to match ...

Board-mounted, split-bobbin, high-isolation power transformers come in open-frame (PSB Series) and shrouded (PVD Series) configurations. The PSB Series is available in six power ratings from 1.1 to 36 ...

As a senior transformer consulting engineer at Doble Engineering Co., Dom Corsi has had the opportunity to inspect transformer factories around the world. He has witnessed the manufacturing of both ...

To prevent similar situations in the future, Chinese engineers have now developed a 750-megavolt-ampere (MVA) smart DC ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...
