Analog simulation of a ferroresonant system including analysis of hysteresis loop

Abstract

In the present paper, we shall develop the analog simulation of electric systems involving saturable core coils. Two cases are analyzed here. In the first one, we consider simulation of the behaviour of a saturable core coil, fed by a sinusoidal voltage generator; we use a mathematical model of the hysteresis loop that enables to select the loop branches without the help of any switching device. In the second case, a more complex one, simulation of a ferroresonant circuit is performed, which contains non-linearities about inductance and losses.
