Analysis of magnetic amplifiers by the use of difference equations

THIS paper explains and illustrates a new way of analyzing magnetic amplifiers through the use of difference equations, and it shows that this method of analysis leads to a different view of the mechanics of operation of the magnetic amplifier. It will be shown that all magnetic amplifiers operate upon the same basic principles, and that these basic principles are demonstrated by the operation of the half-wave, half-cycle-response magnetic amplifier, as is shown in Fig. 1. Furthermore, this circuit can be considered the building-block of all magnetic amplifiers.
