Keywords: Couplings;Coils;Magnetic devices;Coupling circuits;Transform

Abstract: The article analyzes transients in magnetically coupled circuits. The necessity to use the so-called incorrect initial conditions is justified. It is shown how to determine the initial conditions in the case when the coefficient of magnetic coupling between the inductive coupling coils is equal to 1. It is shown how an analysis of magnetically coupled coils can be carried out by studying a converted circuit without inductive couplings. Two examples with different values of the magnetic coupling coefficient M are considered. The results of the analytical solution and the numerical solution are identical.
