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

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.

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

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 ...

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 ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

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 ...

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 ...
