DEFINITION

Classification: 323/324

Using single unidirectional element with bidirectional pass:

(under subclass 320) Subject matter wherein the final control device is capable of carrying current in only one direction but the circuit is arranged in such fashion that both polarities of the input are passed or controlled.

(1) Note. The unidirectional element may be a tube or semiconductive device connected within a diode bridge circuit so as to pass both polarities of the alternating current, or a tube or a semiconductive device bridged by a single diode whereby one polarity of the applied A.C. is controlled and the other polarity is uncontrolled.
