ABSTRACT:
A three phase A.C. to single phase A.C. converter wherein the output voltage is not disturbed if one of the input phase lines becomes inoperative. The three phase A.C. is first rectified, and a D.C. voltage is derived from the resulting rectified D.C. current. The D.C. voltage is regulated, and a single phase A.C. voltage is generated from the regulated D.C. voltage.
