If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...

SolaHD has expanded its industry standard SDN-C power supplies family with the SDN 40-24-100C, a 40A single-phase model that positions the SDN-C Series as one of the broadest available today, now ...

The increasing use of integrated circuits in modern electronic systems has resulted in a growing awareness about lightning overvoltage hazard. The integrated circuits, especially large-scale ...

The course consists of three weeks of materials and is focused on modeling and control of grid-tied power electronics. Upon completion of the course, you will be able to understand, analyze, model, ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

We are often asked if one ACM20 power meter can be used to measure the total current and total real power (watts) in a 3-wire, single phase, 240V AC mains supply with a neutral conductor and two 120V ...
