1. Equivalent circuit design

Transformers are used in a wide range of electrical and electronic applications. These passive components enable energy-efficient adaptation of voltage and current levels to the needs of the application. What's more, they provide galvanic isolation between input and output.

• This dossier focuses on transformers used in power electronics converters. However, the generality of the approaches adopted is such that these studies have already been successfully applied to fields far removed from that of converters, such as the response of a 1 MVA transformer to lightning waves, or the frequency response of a hard disk sub-millimeter...
