A better rectifier arrangement would make use of both positive and negative half-cycles. These full-wave rectifier circuits offer a considerable improvement over their half-wave counterparts. They are not only more efficient but are significantly less demanding in terms of the reservoir and smoothing components. In the simple bi-phase rectifier circuit mains voltage is applied to the primary of a step down transformer which has two identical low-voltage secondary windings. The circuit works like this: On positive half-cycles, the anode of D1 will be positive with respect to its cathode and it will conduct rather like a closed switch. The anode of D'_2_', on the other hand, will be negative with respect to its cathode and it will behave like an open switch. Thus a positive half-cycle of current will be supplied to the load, R'_L_', through D'_1_'. On negative half-cycles, the anode of D'_2_' will be positive with respect to its cathode and it will conduct rather like a closed switch. The anode of D'_1_', on the other hand, will be negative with respect to its cathode and it will behave like an open switch. Once again, a positive half-cycle of current will be supplied to the load, R'_L_', but this time it will flow through D'_2_'. (:nl:)(:table style="clear:both":)
