Flux Reflection Model of the Ferroresonant Circuit

Abstract

The paper presents a linear model of ferroresonant circuit with flux reflection. The proposed model—flux reflection model—derives from observations of typical flux waveforms of nonlinear coil during ferroresonant steady states. Simulation results of the flux reflection model are compared with simulation results of the usual nonlinear model as well as with measurements carried out on the physical model of the ferroresonant circuit. The flux reflection model enables a novel comprehension of the ferroresonant circuit behavior and simplifies the modeling of the nonlinear coil in the ferroresonant circuit.

Unusual Operation of the Junction Transistor Based on Dynamical Behavior of Impurities

“…Taking into account the fact that there is a phase difference between an applied and the resulting current , an angular frequency with a phase angle corresponding to one transit time through the base width is ± = cos( ) ± sin( ), where as long as is valid, higher frequencies are indicated by the inequality ≪ 1, which is used to specify the valid frequency range required for the diffusion of an incremental change of minority carries through [18]. Hence, it is instructive to analyze the transient current paths into the four basic operation modes described by state equations [19]. Such analysis will reveal the electrical parameters into the SJT whose nominal junction transistor model shown in Figure 2(b) is used here to give a qualitative idea of the physics involved to operate the circuit of Figure 1(b) [14].…”
