Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

Three-phase four-switch inverters represent a cost‐effective and efficient alternative to conventional inverter topologies, offering reduced component counts while maintaining robust performance.

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

Keep in mind when reading any article about electrical theory or application that it only scratches the surface of the topic. You can dedicate years of your life to understanding electrical theory and ...

The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...

While applications for 1-Phase PFC are now familiar and prevalent, the same is not the case with 3-Phase PFC. Many equipments using kilowatts of power from 3-Phase mains should be candidates of ...

In the quest for more power efficient data centers, is there any trend in the US to move to 240V/415V three phase power distribution in the data center racks? (or 230V/400V) I would not expect the ...
