The present invention relates to a circuit for supplying a load from an approximately D.C. voltage obtained by rectifying an A.C. voltage, including means for extracting from the rectified A.C. voltage an information depending on a phase angle variation of the A.C. voltage, and a means for making the approximately D.C. load supply voltage independent from the phase angle variation of the A.C. voltage.
