STATIC AND DYNAMIC HYSTERETIC FEATURES IN A PWL CIRCUIT

The general properties of the static and dynamic hysteretic behaviours of a PWL ladder circuit are described and discussed. These properties are obtained on the basis of some results reported in a previous pape r (M. Parodi et al., bit. j. cir. theor. appl., 22, 513 (1994), concer ning the static hysteretic behaviour of the same circuit. Despite the non-linearity of the circuit, the main features of its hysteretic beha viour are shown to depend on the parameters of the circuit components in a simple way. Moreover this behaviour is similar to those observed in a large number of experiments. For these reasons, the PWL ladder ci rcuit is taken as the central element of a general circuit model for h ysteresis. The structure of this general circuit is described at the e nd of the paper.
