Germanium rectifier equipment for electrolytic processes

DIRECT-CURRENT power is being utilized along with alternating current in many industrial systems. Equipment employing sources of d-c power for electroplating, anodizing, electrochemical, adjustable speed drives, and other industrial applications are being used in increasing quantities. It is not convenient generally to power a combined a-c and d-c power system from two separate sources. Available power must either be rectified or inverted so that all electrical needs for a plant can be handled from the same source. The normal direction of change is from a-c to d-c, and it therefore seems reasonable that rectifiers will have considerable importance in the field of design and application for industrial systems.
