An Analysis of Copper-Oxide Rectifier Circuits

THE analysis of circuits containing copper-oxide rectifiers is based upon the selection of a proper representation of the variable impedance of the rectifier element. In this analysis, the element is replaced by 2 constant resistances effective during the 2 directions of current flow through the rectifier. On the basis of this representation, an equivalent circuit is developed, which is a modification of the usual perfect rectifier circuit. The method is illustrated by analyzing circuits in which the loads consist of resistance and inductance and of resistance and capacitance. The computed results are then compared with observations made by an oscillograph.
