Abstract
A rectifying circuit includes a superconductive device and a circuit which controls a magnetic field to be applied to the superconductive device in response to the phase of an A.C. signal applied to the superconductive device, the state of the superconductive device being alternately and repeatedly changed-over between a superconductive state and a nonsuperconductive state by the magnetic field so as to rectify the A.C. signal.
