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 ...

Transformers transfer electrical energy from one electrical circuit to another through electromagnetic induction, with no change in frequency. Like people, they come in all sorts of shapes and sizes.

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 ...

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 ...

The demand for higher efficiency and smaller packages has been the driving force behind advances in switch-mode power-conversion topologies including buck, boost, flyback, forward converters, and ...

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

Are the benefits of digital integrated power transformers worth it? Smart transformers with exciting new technologies like Internet of Things (IoT) and artificial intelligence (AI) are among the next ...

IoT sensors, for instance, can be installed on power transformers in order to collect real-time information on temperature, vibration, and oil level. The data can assist utilities in proactive ...
