Abstract :
The paper describes the development from first principles of a direct electronic analogue of a series-connected self-excited magnetic amplifier. From a closed loop network representing a simple saturable reactor, the introduction of additional windings and feedback to the basic transductor is developed in analogue form. The analogue is a simple and accurate aid to the explanation of the principles of saturable reactors and their application in magnetic amplifiers. The ability to observe the effects of varying any of the parameters, e.g. relative number of turns of the various windings, core permeability, self-excitation and bias, is one of the assets of the analogue both for design as well as for educational purposes.
