ABSTRACT:
A D.C. voltage apparatus providing isolated regulation. A D.C. voltage to be regulated is coupled through a D.C.-D.C. regulator and a D.C.-A.C. converter to the primary winding of a voltage transformer the secondary winding of which is then coupled to a rectifier and filter circuit. A feedback loop including a current transformer coupled to a rectifier and filter circuit and then through a resistive divider to a summer provides an error signal to the D.C.-D.C. regulator. The feedback loop injects into the summer a voltage which is opposite in phase to the output voltage of the D.C.-D.C. regulator which enhances the regulation capability of the device.
