(c) Plate current wave (h) corresponding to time scale of (b). During interval /,current is drawn through the paralleled inductors and the charging tube. At the end ofthis interval the tul)e is cut off and remains so until the start of the next cycle. DuringII, the magnetically stored energy is transferred to the condenser through K2- At thesame time the non-linear coil is brought toward saturation. During III saturation isreached; energy stored in C2 is transferred to the load resistor through L2 in a short pulse. (d) B-H loop of non-linear coil used in the circuit of (a). Letters mark the mostimportant transitions.
