in a television receiver with schaltungsanordnung galvanic netztrennung to suppress zeilenfrequenter störspannungen

摘要

In the television receiver circuit, at least one secondary winding is provided for line frequency interference suppression. A further auxiliary winding (10) is in series with the low voltage winding, (9), wound in the same sense. It is connected through a capacitor (11) in opposite phase to a secondary winding (13). The ratio of number of turns of the winding (9) and auxiliary winding (10) is inversely proportional to the ratio of capacitance between windings (9, 13) and that of the capacitor (11) inserted between the windings (10, 13).
