The use of a copper winding as a temperature sensor for transformer windings is not new. But the circuit presented here goes further. It can make the measurement in-circuit and in real time. The use ...

This test set uniquely combines winding resistance measurement, transformer turns ratio, tap changer dynamic resistance, core demagnetization, transformer type detection, magnetic balance, short ...

This symbol has been the logo for my LinkedIn group, Analog Developments. The image is of a single transformer winding that I needed to make whose turns were arranged on the bobbin as two pi-sections.

Remember back…way back, to linear power supplies. Heavy transformers. Big capacitors. As part of my EDN CDEL build, I’ve decided to use just such a power supply as the front end to the two DC-DC PSU ...

All transformers have nameplates, and all manufacturers use the same nomenclature for capacity, ratings, impedance, and other pertinent information. This article focuses on dry- or oil-type ...

Last month's Code Calculations article covered transformer calculation definitions and some specifics of delta transformer calculations. This month we turn our attention to the differences between ...

Targeted at utility, data center, renewable energy, and industrial markets, Magment’s MagPower-3H offers compact, fire-safe, ...

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 ...
