Magnetic-amplifier design part II - The windings

This development of a practical approach to the design of the toroidal magnetic amplifier is based on synthesizing the design from design charts, thus avoiding the necessity for having available detailed data from previous equipment. Starting with a known power supply frequency, together with a desired gain and time constant, the load voltage and current are utilized in determining the core. With the core specified, additional charts and techniques are presented for the winding layout design. The usual heat transfer and resistance computations serve as a check on the initial design synthesis, and these complete the design process. A straightforward and practical step-by-step design procedure is outlined. This paper, the second of two on the subject, is concerned with the winding layout and the completion of the design. Part I,1 presented the design approach and the method of core determination. Thus, information is given making possible the practical and effective design of the magnetic amplifier having toroidal construction.
