This circuit uses four similar diodes in which opposite pairs conduct on alternate half-cycles. This arrangement avoids the need to have two separate secondary windings (as in the bi-phase rectifier circuit). On positive half-cycles, point A will be positive with respect to point B. In this condition D'_1_' and D'_2_' will allow conduction whilst D'_3_' and D'_4_' will not allow conduction. Conversely, on negative half-cycles, point B will be positive with respect to point A. In this condition D'_3_' and D'_4_' will allow conduction whilst D'_1_' and D'_2_' will not allow conduction. As with the bi-phase rectifier, the switching action of the two diodes results in a pulsating output voltage being developed across the load resistor, R'_L_'. (:nl:)(:table style="clear:both":)
