This report describes a practical current regulator system used to accurately control the current delivered by a 500 kilowatt motor-generator unit. The generator supplies its current of 2000 amperes at 250 volts to a large water-cooled air-core solenoid used by LASL Group P-7 for experiments in connection with the Sherwood program.
After a general discussion of the system specifications and the basic regulator loop, each of the components in the basic regulator loop is described in considerable detail. The description, in most cases, is mathematical in nature although many circuit diagrams are included with brief descriptions when necessary for proper clarification. Included in the description of the components are experimental data and graphs required to properly determine and describe the characteristics of these components.
The mathematical descriptions of the basic components form the foundation for the derivation of the regulator system differential equation. The convenience of the Laplace Transform method is illustrated in this derivation. In making a determination of the stability of the regulator system, several different criterion are used. These include the Routh-Hurwitz criterion, the Nyquist criterion and the Bode diagram technique.
