A voltage regulator for flyback-type high voltage supplies having a supplementary energy storage transformer with its secondary interconnected in series with the primary of the conventional flyback transformer, a control circuit for sensing (a) the generation of the conventional flyback pulse, (b) a reference voltage, and (c) a feedback voltage signal appearing at the output of the conventional flyback transformer and a switch for selectively applying energy to the primary of the supplemental energy storage transformer. The aforesaid switch being activated whenever the feedback voltage is less than the reference voltage and said switch being activated earlier in time as the aforesaid difference becomes greater. Just after the occurrence of the flyback pulse, the switch is opened to permit energy in the energy storage transformer to be placed on the primary of the flyback transformer so that it is added with the flyback pulse to maintain the resultant voltage at the output of the secondary conventional flyback transformer at a regulated value.
