Note: Author’s signature redacted from title page. The percentage of D-C motors being used in industry is greater than ever before. One reason for this is that in the last twenty years the development of the electronic tube rectifier has facilitated the economical conversion of A-C power to D-C power. The recent improvement of dry disk rectifiers, particularly selenium rectifiers, suggests that they may soon seriously compete with tube rectifiers in many applications. The writer has attempted in this thesis to do two things. Firstly: to outline the theory of rectification, dwelling particularly upon the advantages and disadvantages of the commonly used rectifier circuits. This material has been augmented with numerous oscillograms which are so often lacking in texts and technical literature. Secondly: to point out the advantages and disadvantages of dry disk rectifiers as applied to rectifier-motor drives. This work is not original, but rather a compilation of information found scattered throughout the literature. The use of a multi-rectifier-motor drive is suggested; this type of drive has not, to the writers knowledge, been discussed elsewhere in the literature. Time limitations have made a study of this drive impossible. |
