摘要

A television apparatus, for generating a deflection rate parabolic auxiliary deflection current that corrects convergence distortions, includes a deflection generator output stage coupled to a deflection winding. The deflection generator output stage generates a trace scanning current during a trace interval. The primary winding of a transformer is coupled in a current path of the trace current. A parabolic voltage developing capacitance is coupled across a first secondary winding of the transformer. The trace scanning current in the primary winding of the transformer causes a deflection rate parabolic voltage to develop across a second secondary winding of the transformer. The parabolic voltage across a second secondary winding of the transformer is used for generating the convergence distortion correction current.
