When comparing the kilovolt-amp demand loading on Southern Company substations with the actual connected transformer nameplate kVA, it was apparent that, on average, the distribution transformers were ...

Part 2 of our QSPICE tutorial explores simulation in the transient domain, an essential feature for understanding the behavior of circuits over time. We will cover the simulation of a DC power supply.

Transformerless power supplies are showing up a lot here on Hackaday, especially in inexpensive products where the cost of a transformer would add significantly to the BOM. But transformerless power ...
