Voltage control of vapor rectifiers

Some of the changes to be introduced into the mathematical treatment of rectifier circuits when the firing of the anodes of a rectifier is advanced or retarded by control of the arc are described. The points considered and illustrated by theoretical curves include commutation between anodes, regulation, and wave shape of the output voltage for the more usual transformer connections, and resulting variations in functions of the transformer reactance and of the nature of the d-c load.
