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 ...

An internal fault can be violent enough to blow the lid off a transformer. Catastrophic failure of an overhead transformer is a rare occurrence, but it does happen. Electrical systems are designed so ...

Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...

Here are the steps required to select the transformer and how to design the circuit needed to meet the end use in a manner that prevents transformer saturation Average current-mode control (CMC) ...

A core-balance protection device serves as an example of how these switches operate. Phase and neutral power conductors pass through a toroidal (differential) current transformer. Under normal ...
