When alternating current (AC) prevailed over direct current (DC) in the late 1800s, one of the deciding factors was the need for voltage levels to be raised and lowered throughout the power system to ...

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 ...

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 ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

Editor’s note: I am pleased to bring you this excellent tutorial by Steve Subiry, Global Products Manager for Magnetics at Eaton. Enjoy. Magnetics are essential components in power topologies but they ...

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 ...
