Using a flyback topology to generate a high voltage is a common approach. The voltage can charge a capacitor for a high-energy pulse. Such an approach is used in defibrillator capacitors, photoflash ...

Download this article in PDF format. If you search the internet for “transformer equivalent circuits,” you’ll get five pages of over 100 small circuit diagrams. Figures 1 and 2 show two typical ...

A transformer transfers electrical energy from one system to another by induction. Except for grounding and bonding connections, there’s no physical connection between the two systems. For this reason ...

In Part 1, we looked at how to size a branch circuit and walked through a simple example. So if you’re sizing a feeder, why don’t you do it the same way? Except in cases where a feeder is also ...
