Theory of rectifier — D-C motor drive

THE use of rectifiers for furnishing power to d-c motors is becoming more common, particularly for variable-voltage drives. The theory applying to drives such as those incorporating the Ward Leonard system is quite inadequate for use with a rectifier-d-c motor drive. This paper is an introduction to the theory involved when operating a d-c shunt-wound motor from a rectifier. It is hoped that further thought and discussion of this new and vital subject will be stimulated.
