It is important for machine design engineers to understand how transformers work so they can design machinery that operates optimally within the proper voltage ranges, as well as select the right ...

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 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 ...

Can one transformer make power systems smaller, lighter, and stronger for space and defense use? Engineers may want to see ...

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 ...

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 ...

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 ...

One of the most dangerous locations in a power distribution system with regard to incident energy is that first panelboard on the secondary of a transformer. With some thought in your design — even if ...

Geo-magnetically induced currents (GIC) have a bad reputation. Download this free white paper and learn the true effect of GIC on power transformers, based on thorough knowledge of power transformer ...

Small, isolated power supplies provide power across isolation barriers in applications from electric vehicle traction inverters to factory control modules. In this Power Tip, I’ll examine different ...
