ABSTRACT:
A constant voltage converter for use with a cathode ray tube in which a voltage regulator is controlled by both the output of the regulator and beam current from the cathode ray tube by way of beam detecting means. The output of the regulator is applied separately to a stabilizing circuit including another feedback circuit for CRT, and also to deflection circuits so as to better prevent fluctuation of picture on the CRT.
