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

It is frequently advantageous to employ a transformer-less power supply solution to provide the required supply to low-power circuits. In fact, it is possible to convert the input AC voltage into DC ...

Power transformers are often the main source of common-mode noise in isolated switching power converters. Why? Because inside the transformer, the windings on the primary and secondary sides of the ...

In PoE systems, performance of the flyback converter used to step down the 48-V supply in the powered device depends on careful transformer design. A growing number of electronic devices require both ...

The effort is part of Hitachi Energy’s $9 billion global investment program to expand manufacturing capacity, R&D, and ...

Transformers are the backbone of reliable power for utilities, industrial sites and large construction projects. When a ...

Sumida Corporation has introduced two new pulse transformers, the CIUH10D46 and CIUH10D47, designed for use in advanced ...

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 ...

Hitachi Energy will invest an additional CAD 270 million (USD 195 million) to expand its power transformer manufacturing facility near Montreal, Canada. The expansion builds on a project announced in ...
