International technical platforms such as the IEEE PES Transmission & Distribution Conference and Exposition play a key role in shaping these developments by bringing together grid operators, ...

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...

In LLC Power Conversion Explained, Part 2: Sine Wave from a Square Wave, a basic square wave Switched Mode Power Supply was shown to be filtered from a square wave into a sine wave. This resulted in a ...

Vanguard Instruments Co. has added two new products to its family of transformer turns-ratio testers: the ATRT-03 S2 and the Tri-Phase May 6, 2008 Vanguard Instruments Co. has added two new products ...

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 ...

The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

Elsco Transformers reports that choosing the right transformer size involves calculating kVA based on voltage and current for efficient operations.

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

Designing flyback transformers for switch-mode power supplies involves many calculations. A spreadsheet can make short work of this otherwise-tedious task. When you develop flyback power supplies, ...

The technology promises to replace several parts of the grid with one device that’s both controllable and updatable.
