摘要:
A step-up coil of a high-voltage transformer for powering a cathode-ray tube comprises windings housed in chambers (79) of a coil former (72). These windings are made in pairs (55, 56). The inner end (57) of the first winding of the pair is connected to an electrode (58, 60) of a first diode (59), the inner end (61) of the second winding of the pair is connected to the electrode (62, 64) of like nature of the second diode, or alternatively, the outer end (75) of the first winding (51) of the pair (55, 56) is connected to an electrode (58, 60) of the first diode (59), the outer end (65) of the second winding of the pair being connected to the electrode (62, 64) of like nature of the second diode (63).
The inter-winding capacitances of the windings of the pair are thus non-activated, the corollary of this being a decrease in the value of stray oscillations of the output voltages.
