The behavior of rectangular hysteresis loop cores in every application

An analysis of the behavior of a rectangular loop core when switching from one to the other of the two remanent states is presented. The paper is divided into two parts. In the first part the properties of the first pulse and of the main pulse relative to a step driving current are described. From these properties the terminal characteristics of a core under arbitrary drive and load conditions can be deduced. In the second part some simple graphical procedures to calculate the output voltage in an arbitrary drive and load condition are suggested. The experimental curves relative to resistive, inductive or capacitive loads are in a very good agreement with the calculated curves. Furthermore, some important terminal characteristics (as peak amplitude, peak time, switching time) are plotted vs load parameters (R, L, C).
