Abstract:

The method of establishing differential equations with self-induction and mutual-induction electromotive force and the method of establishing voltage-equilibrium equation and magnetic-potential equation with magnetic flux are related and compared in this paper. The consistent results indicate that the former method can be used to study not only iron-core transformer，but also non-core transformer, and therefore, is a basic analytical method.
