Abstract
The magnetic circuits of a current converter, the work principle of which is based on the nonlinearity of the magnetization curve, are considered. In order to improve the analytical calculation accuracy of magnetic circuits, it is necessary to establish a relationship between the specific magnetic resistance and magnetic induction. Methods for solving differential equations for magnetic circuits of a converter with longitudinally distributed parameters and an expression for the dependence of the specific magnetic resistance relative the magnetic induction are presented.
