ABSTRACT:
To decrease the internal resistance of a transformer operable as a television line transformer of the "diode-split" type, the secondary winding sections are matched to each other and to the frequency of operation of the transformer in such a manner that the current in the respective sections will flow at respectively different instants of time; in a preferred form, the winding sections, on the average, are tuned to a harmonic of the frequency of the signal applied to the primary and are positioned on winding forms or holders such that the distance between the bottom wall of the primary and the bottom wall of the secondary is constant over the entire length of the windings. Preferably, the tuning of the respective winding sections is effected by matching of the primary winding to the secondary within the region of the secondary winding sections.
