Abstract
In a deflection system including an oscillator and an amplifier providing scanning current for a deflection winding, a parabolic voltage developed at the deflection winding is superimposed on the oscillator direct current operating voltage in such a proportion that an increased parabolic voltage level, indicative of excessive scanning current from either an overscan or low operating frequency condition, causes the oscillator to operate at a higher frequency which decreases the deflection winding current and therefore the parabolic voltage and thereby permits the use of less expensive circuit components having lower maximum voltage level ratings.
