Power-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.

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

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 ...

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 ...

A solid-state transformer (SST) is an AC-AC converter, sometimes called a power electronics transformer (PET), that replaces ...

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 ...

Hyosung Chairman Cho Hyun-Joon Aims to Make the Memphis Power Transformer Plant the Largest Transformer Factory in the U.S.

For one-off projects or prototyping, it’s not too hard to find a wall wart or power supply to send a few joules of energy from the wall outlet to your circuit. Most of these power supplies use a ...
