ABSTRACT:
The high voltage power supply for the CRT display of a computer system is modified by the addition of tightly coupled, unitarily wound secondary windings feeding current to rectifier diodes oriented to conduct during the horizontal scan. These secondary windings and diodes provide a stable, regulated source of D.C. power for the remaining modules of the computer system.
