Computer Design of a Class of Multiple-Output SCR AC--DC Systems

A primary-controlled multiple-output silicon controlled rectifier (SCR) system is presented which requires only one output unit to be contained within the control loop; all others are slave to it. Design equations based upon a new theoretical model for SCRs are derived which provide the designer with both the static and dynamic response of the individual output units to steps in line and/or load. A computerized algorithm for the design of these output units is suggested and illustrated with an actual example.
