Abstract
A boost capacitor has a first terminal that is coupled to a retrace capacitor of a horizontal deflection circuit. A diode couples a trace voltage in an S-shaping capacitor to the boost capacitor to charge the boost capacitor during trace. A second diode rectifies a voltage that is equal to the sum of the boost capacitor voltage and a retrace voltage developed in the retrace capacitor for generating a screen grid voltage for a cathode ray tube.
