Unlike the voltage transformer, a current transformer measures current from one circuit to another, which requires different calculations to create the optimal design. Current transformers measure ...

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 standard for precise current measurement in instrumentation and other high reliability equipment applications has been the current sense transformer. They are accurate, easy to implement, and ...

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 ...

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 ...

Current transformer (CT) saturation presents a critical challenge in the realm of power system protection and automation. Under fault conditions, the magnetic core of a CT may become saturated, ...

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 ...

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. The rapid buildout of fast-charging stations for electric vehicles is testing the limits of today’s ...

In many electrical installations, general-purpose contactors are used to switch the supply voltage to a small dry-type transformer on and off. One common reason this is done is for area lighting ...
