Charge control of magnetic amplifiers II ¿ The performance of self-saturating magnetic amplifiers

The treatment of the magnetic amplifier as a charge-controlled device, consistent with its mechanics of operation, makes possible a simple and unique description of various circuits. Better insight into the details of the self-saturating magnetic amplifier´s operation and performance is attained, whereas the generality of the approach is conserved. This is mainly a result of the general regularities of the physical nature of core material behavior, which are here taken as the starting point of analysis. The charge control approach is novel with respect to magnetic amplifiers; however, the standard technique of core testing according to Roberts´ method is shown to be applicable, receiving a new generalized interpretation.
