The effect of initial conditions on subharmonic currents in a nonlinear series circuit

This paper shows the importance of switching time as an initial condition for the current in a simple nonlinear series circuit with a saturable inductor. It is also shown that initial flux linkages in the inductor have an important effect on the current response during the first few cycles after closing the switch. It is emphasized that all experimental work was done with voltages below the critical ferroresonant voltage.
