The rectifier calculus

F. O. Stebbins (General Electric Company, Schenectady, N. Y.): The rectifier calculus as described in this paper makes available to the designing engineer a greatly simplified method for computing many of the characteristics of mercury-arc rectifiers such as output direct voltage, regulation, etc. We have checked some of the formulas developed in this paper and find them to be entirely correct for balanced supply-system voltages. Also they present a considerable saving in time and effort over conventional mathematics. In addition these formulas are no more complicated when the supply-system voltages are unbalanced whereas the solution of unbalanced rectifier circuits with conventional mathematics is somewhat laborious.
