In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

Most petrochemical industrial facilities have numerous small (30kVA or 45kVA) transformers spread throughout the process units serving lighting and power distribution panelboards. In the U.S., the ...

Download this article in PDF format. If you search the internet for “transformer equivalent circuits,” you’ll get five pages of over 100 small circuit diagrams. Figures 1 and 2 show two typical ...

As fuel costs continue to rise and power outages become more prevalent around the country, the necessity of utilizing energy-efficient products of all types is becoming universally recognized.

This gate-drive transformer (GDT)circuit allows the drive signal to the MOSFET to range from 50% down to 0%, while still offering a fast turn-off that cannot be accomplished with a simple load ...

The basic schematic of an electronic transformer (ET) includes a traditional full-bridge rectifier, a self-oscillating chopping circuit, and an output-power transformer. The self-oscillating circuit ...
