9.4.1 Operating Conditions: Misleading Behavior of Differential Current Power transformers are energy storage devices that experience transient behavior of the terminal conditions when the stored energy is abruptly changed. Such conditions may be seen during transformer energization, energization of a paralle...
First, let’s remind ourselves of the basics in a few sentences. That is something you must know. A current transformer (CT) is designed to produce a secondary current which is accurately proportional to the primary current. It consists of a single primary winding, which an external busbar ...

Figure 5. This illustration contrasts the ripple produced by the circuit of Figure 1a vs. the circuit of Figure 1c assuming both are optimized for a minimum acceptable off-time. Efficiency Considerations There are three main efficiency losses to consider in the transformer topology. Transformer/indu...
