Development of a mathematical model of a current converter with nonlinear magnetic resistance

Abstract

A mathematical model of a current converter with nonlinear magnetic resistance has been developed, which makes it possible to increase the accuracy of the analytical calculation of magnetic circuits, taking into account the relationship between the specific magnetic resistance and magnetic induction. Methods for solving differential equations of magnetic circuits of a current converter with longitudinally distributed parameters are applied. An expression is obtained for the dependence of the specific magnetic resistance on magnetic induction.
